PermGen space error....
Locked
 
|
Config:
CentOS 6.2 x64 Dual Intel XEON 3.07 Ghz CPU (VMWare ESX 5 host) 4 GB RAM Tomcat 6 Sonar 3.0.1 JDK 7 update 03 Tomcat startup:
-verbose:gc -server -Xmx2048m -Xms512m -XX:+CMSClassUnloadingEnabled -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:MaxNewSize=256m -XX:MaxPermSize=1536m -Dcom.sun.management.jmxremote -Dfile.encoding=UTF-8
I restarted the application Friday afternoon due to this issue and bumped the MaxPermSize from 1024m to 1536m and this morning Sonar is reporting PermGen memory errors again.
Any idea what I am doing wrong? I don't believe our SONAR usage should be overloading SONAR. I do have about 15 projects that run SONAR after every build in Jenkins, but most are small library projects or smaller service applications.

Hi Jeff,
On Nemo, Sonar is running with -XX:MaxPermSize=128m so we should find out why this is not the case on your side.
Are you executing any dynamic language like Groovy on the Tomcat instance ? Kind regards, Freddy -----

Thanks,
We aren't using Groovy or anything else directly that I'm aware of (unless it is happening due to a plugin) and Sonar is the only web app (besides the default tomcat manager) running on that server.
Here are the list of plugins:
System plugins
I cleared all the logs when I restarted this morning so if/when it happens again, I'll pay close attention to the error context.

Here is a snippet of the error I see in the catalina.out file:
Are they related maybe?

Is Sonar the only thing running on that Tomcat?

Hi Jeff,
I'm sorry but I really can't manage to understand how Sonar could consume so much permgem space. When have you started to face this issue ?
Thanks Freddy

Hard to say.
It's a new deployment of Sonar 3.0.1 (as of about 7-8 weeks ago) and it has happened with increasing frequency as we have converted all our projects to Maven and enabled Sonar analysis.
All our active projects are now "Mavenized" and running Sonar as part of the Jenkins post-build steps. I have to restart tomcat about every 5-7 days now. The last time was yesterday (7/12). The time before was Friday (7/6). We have 22 projects showing in the sonar results. 3 are C# that have been added by another team that is prototyping Sonar with their builds.
I'd say that our Sonar is lightly used compared to some so it is baffling. What can I enable to get more usage or debug info?

Hi Jeff,
I would like to be sure that this issue only relates to be the Sonar core so would it be possible to use the Sonar standalone mode instead of deploying Sonar on a Tomcat server ? Thanks Freddy -----

I can try...it is in production now and has DNS and such configured that I don't control. I've also never run the stand-alone version so I don't know what it might require to swap out without changing too much infrastructure and I'm out all next week.
I'll try to work on it after that. In the meantime, if there are any suggestions regarding more debugging/logging options I should try, I'm all ears.

So I haven't had time to try the stand-alone, but hit the error today. I saved off the logs if they would be of interest.
