Red Alert 2 Fatal Error
Destini Armstrong
I was using RStudio regularly and all was working smoothly..But recently my Windows crashed terribly and had to be restored to a previous time. Thereafter, when I opened RStudio, my project is not opening ad repeatedly showing the error Java Script alert R encountered a fatal error. This session was terminated.I am sure I had closed Rstudio properly the time I had last used it before the Windows crash. Can anyone tell me how I could solve this problem(preferably without losing much data and work on RStudio)
And delete the file history_database. (For someone in linux, search the folder .rstudio) You will NOT lose your open files history or environment history. You may have to change your default folder, and open manually its .Rdata file, in order to get the last environment you saved. Ex.: load(paste0(getwd(),"/.RData") )
I'm seeing some instances of "Received fatal alert CertificateUnknown from client" errors in the decryption log when the root\issuer certs are clearly in the FW's cert store. Attached are screenshots of the error and the FW's cert store. Any ideas on what could be going wrong here?
Hi Satya, you are quite correct. When I exported and opened the original cert in the screenshot, it was in fact only an intermediate cert. I was able to download the root and install it. Thanks for setting me straight!
Regrettably, as I go over the decryption logs again today, I'm still seeing instances of my original issue. For example, here's the error in the decryption log (I should note that the source IP address from this entry is assigned to one of our corporate laptops, and thus trusts the forward-trust certificate):
Is this running from an application on the clients machine or are they just web-browsing to this place? Generally in my experience client cert errors are most often a result of the application doing certificate pinning thus causing ssl inspection to stop this connection.
You know, that's a good question. I don't really know anything apart from what I see in the decryp logs. Just trying to be proactive so people don't write helpdesk messages saying they can't get to this or that site... Is there a way to tell?
However, this is not the case when this website is loaded via another website - it appears that the sophos tries to perform the SSL/TLS validation on the CNAME itself, which fails, rather than the destination, which has the correct certificate:
Is this to be expected, and the only recourse is to exclude these addresses from SSL/TLS decryption as they arise? Should the Sophos appliance not be resolving the CNAME to the correct address before performing the TLS inspection, or is this happening on the browser side beyond our control?
Hello ScHwAnG86,
Thank you for reaching out to the community, based on the error: " fatal alert certificate unknown(46)" - This is the browser refusing the communication. have you tried with different browser ? To fix this problem is to use a certificate trusted by the browser. In case of a self-signed certificate this means that you either have to import the certificate into the browser as trusted (in which case Subject Alternative Names in certificate must match the URL) or you add an explicit exception at the warning dialog you get when visiting the site.
Hosting is GoDaddy, shared account. Not using email for replies, only the sign in ticket system. Therefore I don't believe any cron jobs are involved, as I didn't do anything but the automated install.
Sounds like someone's trying to access the ticket system (either as a staff member or a client/visitor going to the public side of things), osTicket is unable to connect to the database (based on the subject of your post) and emailing you an error message. That explains the randomness of it.
As to the occasional inability to connect to the database, this is a common problem with shared hosts and isn't really unique to osTicket, it's just that osTicket lets you know about it when it happens.
What happens is that the hosting company will limit the number of simultaneous database connections allowed on the machine and if someone tries to connect while that's maxed out, they get the error. This happens more frequently with servers that have a lot of traffic or machines with a low limit.
It does not matter if anyone is signed into the support system or not. I've received email alerts at 4am when nobody is doing any support. I also checked for anyone opening a support ticket at the times of the error. No obvious culprit.
Its shared hosting, but the account is not being hammered with traffic by any means. I have a couple other database applications, which are working fine and are of much higher demand than the sporatic use of the ticket system.
Sure would be nice if the error message would say WHAT is trying to connect to the database so I would have some idea if its a file screwed up on the server, outside access, or the hosting account can't handle the 3-5 tickets we get a day! (seems pretty pathetic that would bog the server down)
That is the only instance of that error message so this is definitely the code that is triggering the alert. So its either unable to connect to the database or its unable to select the database once connected. As to why, I couldn't tell you. Perhaps there is a hint in mysql logs or maybe apache logs (but I'm not sure if it would show up there).
How i understand this alert came with an error that doesn't accept certificate. I use Splunk's build in certificate, and dont know why this error shows up. Could this error be due to server overload or lack of resources? Because in other environments with the same settings this error doesn't show up.
Currently I configured event alerts though SQL agent severity 025 fatal error" to email DBA group . Every day network security process is running and that will kicked off SQL agent severity 025 fatal error" to email DBA group . this is bit of pain . So how to exclude this process to kick off this even email. SQL Server identify the network security process as "025 fatal error"
Did you mean network security process will trigger the SQL alter and sent the email notification to DBA email group? How did you define the SQL Server Alert? What will trigger the alter that you defined? Did you get any useful information from SQL error log?
Severity 25 Errors--- A severity 25 error is a fatal system error. I have heard that severity 25 is more or less a catch-all for miscellaneous fatal errors. I have only seen this error when related to failed upgrades: something prevents one of the upgrade scripts from running, and a severity 25 error is thrown. Quote from this blog Dealing with high severity errors in SQL Server.
You can't specify what you want an alert for all error in a certain severity level, and then exclude specific messages within that severity level. (A long long time we could do that by entering those error numbers in a specific place in the registry, but that is long gone).
I would make sure that this doesn't happen, in the first place. Why do the SQL Server throw that security, and reconfigure whatever is triggering it so it doesn't happen anymore. 25 is the most sever severity level!
The Foreign Trade Regulations (FTR), 15CFR, Part 30.5(e), authorizes the Automated Export System (AES) Branch to identify inconsistencies in AES data and to make recommendations that will result in the appropriate corrective actions by the filer. The AES Compliance Report is an important component in this process.
Beginning in April 2012, the AES Compliance Rate was adjusted to include outstanding fatal errors. The AES Compliance Report displays the details of shipments with unresolved fatal errors including the Shipment Reference Numbers, AES Response Codes and AES Response Narratives. The report also provides a listing of the most frequent unresolved fatal error(s) and their associated reason(s) and resolution(s).
A Fatal Error message is sent by the AES when invalid or missing data has been reported, the EEI has been rejected, or when the information is not on file in the AES. The filer is required to immediately correct the data and retransmit the EEI.
A Warning message is sent by the AES when additional data is required on a filing but the filing is accepted. If the EEI is left uncorrected, AES will generate warning reminders to the filer until the correction is made.
A Verify message is sent by the AES when shipment data conflicts with a U.S. Census Bureau parameter regarding a commodity or another unlikely condition is found. The EEI may or may not be correct. The filer is required to transmit a correction if a correction is warranted.
Filers who frequently receive AES Verify messages may submit a Parameter Change Request to EID.param...@census.gov. In order to submit your request, your company must use the Parameter Change Request Form.
During SSL/TLS handshake failures, you may notice a SChannel event being logged in the System event logs. A closer looks provides that there is a number associated with these failure messages. The logging mechanism is a part of the SSL/TLS Alert Protocol. These alerts are used to notify peers of the normal and error conditions. The numbers especially, play a trivial role in understanding the problem/failure within the SSL/TLS handshake. SChannel logging may have to be enabled on the windows machines to get detailed SChannel messages. Please refer the following article to do so:
There is MSDN article which describes these messages more briefly. Here is the link: -us/library/cc783349%28v=ws.10%29.aspx. However, the article never mentions the alert codes while explaining the messages. For simplicity, I have created a simpler table combining both the MSDN documentation and the RFC for usability. Below is the table:
This is not a technical question but operation management practice question. I understand Pega writes ERROR or FATAL in case any error occurs in application. You can look at it from log file directly, or use some monitoring tool like ELK. In my previous project, since customer's monitoring system watches ERROR and FATAL string in log file, whenever it is recorded, it goes to system administrator, and they will look into details. Obviously with this operation, a bunch of ERROR have to be reviewed during development and many of them have to be added into the "ignorance list", otherwise it will end up with phone ringing every day. But anyways, we did this time-consuming job and some of them, developers fixed the code, and some of them, we decided to ignore it. I did this approach, but is this something that people do around the world? It was a very time-consuming job, so I don't think everyone is doing the same. Maybe people just develop it, and no monitor in log file? If there is any standard practice on log watch policy with Pega, please let me know.
