Cache manager error using Railo 4.0 beta 2

[Zenom]

Hello,

Yesterday I've installed Railo 4.0 beta 2 for testing purposes, and at first it was really nice, and a lot faster. But when I tried to access a second application, it threw an error saying that an unnamed cache instance was already running and the second application did not start. Using Railo 3.3 this issue does not occur. Here's my setup:

Apache 2.2 + Railo connector

Railo 4.0 beta 2 (with tomcat) - fresh install

Also, here's my applications setup:

My applications are inside different folders and every one of them has an Application.cfc file that extends from another one that is common between all applications. When I run any of these applications right after starting Railo, they run normally without any issues, but all the other applications start throwing the Cache Manager error. I've tried to use a separate ehcache.xml for each application, but it did not work. Any suggestions?

[Zenom]

Anyone?

[Matt Quackenbush]

I've never seen anything like you're describing. I am also guessing that folks are going to need a lot more information from you in order to steer you in the right direction.

* What is the exact error message?
* What is the stack trace?
* Can you recreate the issue in a very simple test case that folks can run and check against?

I'm sure there will be other questions, too, but the answers to those should help quite a bit.

Tom,

Did you ever find a solution to this problem? I've run across the same issue. I'm currently running 4.0.2.002. I installed EhCache through the extensions. The first cache setups fine but as I add a second cache I receive the errors. After the second one is added, you cannot verify either one of them through the Railo admin without receiving an error.

Thanks,
Joe Brislin

I'm getting exactly the same error. I'm using the EHCache add-on (not EHCache-lite).

I can really only get one cache working; as soon as I add another cache, the server poops - I get nullPointers everywhere, and I have to remove the second cache otherwise absolutely nothing works.

Interestingly, when I add the first cache, it works, but I get this in the logs:

SLF4J: The requested version 1.5.5 by your slf4j binding is not compatible with [1.6]

After reading the EHCache install.cfc, it says: "you cannot install ""EHCache"" and ""EHCache Lite"" at the same time, please first uninstall ""EHCache Lite"", to install ""EHCache"".

However, EHCache-lite isn't an extension in Railo 4, it looks like it's core - so how would I get rid of it??

When I add the second cache, in the Railo logs I get the following:

net.sf.ehcache.CacheException: Another unnamed CacheManager already exists in the same VM. Please provide unique names for each CacheManager in the config or do one of following:
1. Use one of the CacheManager.create() static factory methods to reuse same CacheManager with same name or create one if necessary

I've had this issue, which seems to have been fixed in the bleeding
edge version (4.0.3.004). It is bleeding edge, but I've been using it
for development and been stable.

That's got it working. Thanks John. Unfortunately, it's not optimal being a production server but it's looking like it will have to do for now.

I'm not aware that we did a fix for this, can you please open a ticket in jira

Tnx Micha

Sorry for the confusion Micha & Joe, when I say fixed, I mean it seems
to be working now, rather than a specific bug fix had been applied to
make it work :)

[Joe Brislin]

Micha,

I entered a JIRA issue for this since I have been able to replicate it on multiple platforms. The current stable version (4.0.2.002) is affected but it is working in the current bleeding edge version (4.0.3.004).

https://issues.jboss.org/browse/RAILO-2296

[Igal @ getRailo.org]

hi Joe --

so just to confirm:  in 4.0.3.004 you can not replicate this issue?


Igal

[Joe Brislin]

Yes that is correct. Since I've upgraded to 4.0.3.004, I have not been able to replicate this issue.

I am seeing something similar when I startup web contexts in parallel using Tomcat parameter startStopThreads on the Engine tag.  Without this it starts without exceptions.

I'm just using ehcache built into Railo for session cache.

Railo version: 4.0.4.000

Phil

[Tjarko Rikkerink]

This is again happening with 4.0.4.000 installed this morning and crashed most of my servers within minutes.

Nullpointer errors, cachemanager stops, TimeToIdle errors... you name it.. everything was flying by in no time.

[Michael Offner]

We need more details to help you

Just upgraded from 4.0.3.005 to 4.0.4.001 and the issue is back.

Here's the info:

Rolling back to 4.0.3.005 does not fix the issue (even after a restart), even though it was working prior to upgrading from 4.0.3.005 to 4.0.4.001.

As a side note - is thgere anywhere where I can download old releases like 4.0.3.005? I tried to modify the download URL but it didn't work.

Thanks!

[Igal @ getRailo.org]

you can download an older version from http://www.getrailo.org/index.cfm/download/olderversions/

do you create cache regions in your code?  can you show the code snippet that triggers this error?  could a simple fix be to use #Application.ApplicationName# as the name for the Cache object so that no more than one unnamed cache object is created?

[Joe Brislin]

John,

Do you have the secondary cache enabled in ORM? I had figured out that this being enabled triggers the error that you posted. 

Thanks,

Joe

Hi Joe,

Yes, 99% sure it's the second level cache in ORM that's doing it. 

Cheers,

John

[John Whish]

Thanks Igal - that's really helpful.

I almost certain it's the hibernate second level cache that's doing it - it was last time I saw this error. I don't believe I can specify the cache name that hibernate uses?

- John

[Igal @ getRailo.org]

I am actually not sure.  I am not a big fan of ORM myself.

Denny had some comments on this issue a few weeks back on the JIRA.  read the comments at
https://issues.jboss.org/browse/RAILO-2233 and see if it helps.

also, maybe Joe can shed some light with how he resolved this?


Igal

[Joe Brislin]

I actually have not been able to resolve it yet. I've had to temporarily turn off the secondary cache for ORM.
