Transient object container session_data in event.log

[hrydziusz...@gmail.com]

Zenoss 4.2.3

I have a few issue in the event.log

2022-04-26T12:53:33 WARNING Transience Transient object container session_data max subobjects reached

A few, I mean hundreds thousand...

[root@zenoss_server /opt/zenoss/log]# fgrep "Transient object container session_data" event.log | wc -l
579969

Someone can to explain this?

Thanks in advance.

This is rather a guess but "session" makes me think of the zodb_session transient database, which you can throw away and recreate.  Note - I would make sure I had a backup position before doing this, though I have used it several times and it hasn't bitten me yet ;)

Look on the zenoss wiki at http://wiki.zenoss.org/Troubleshooting_Zenoss_PosKey_Errors   for instructions that match Zenoss Core.  If you have the chargeable Resource Manager version, there is an article at https://support.zenoss.com/hc/en-us/articles/203075445-How-To-Clear-The-Zends-zodb-session-Table   that matches better.  Clearly, if you have changed user names / passwords / permissions on your SQL database then you will need to substitute the correct values.

HTH,

Jane

Well, it didn't help :(

I found something else that I didn't see before.

Should I find setting for this in /opt/zenoss/etc/zope.conf ?

I have no chargeable Resource Manager version, just Zenoss Core.

OK. The other thought on "transitional data", given that it is sendEvent that is wingeing, is that it might be the event log indexes.  Check here  http://wiki.zenoss.org/index.php?title=ClearEventIndex&oldid=13954    for details.  Usual caveat applies ;)

Cheers,

Hi,

I waited a few days to check if my instance of Zenoss works correctly.

It looks that I had to set "maximum-number-of-session-objects" parameter in the first step and next to drop "zodb_session" database.
No errors found in the logs files now.

Jane, big thanks for your help.

Case closed.

Regards,

Tommy

Glad you got there, Tommy :)  Just for the record, where did you set that patameter for "maximum-number-of-session-objects" ??

Cheers,

Jane

This parameter can be set in the "zope.conf" file. The full path is "/opt/zenoss/etc/zope.conf"
