PermGen issue

[vishad alekh]

Hi All,

I am using Jenkins 2.11. My Jenkins is frequently going down with permGen issue.
Even if I am not executing any jobs.
My server configuration is pretty good too.

Can someone please assist with the possible reason for the same. Or any way in which this can be resolved.

I have tried increasing the permGen space by passing parameter at the time of startup but no luck.

Maven configuration is also done for the same.

Please assist.

Thanks and Regards
Vishad Alekh

Out of curiosity are you using Multibranch Pipeline heavily? The fact that
you're having a PermGen issue means you're likely running on JDK7, can you tell
us anything else about your environment?

Hi,

Yes, I am using multi branch pipeline and also jdk 7. 
Actually I have made build n compilation job for 3 application. There is a master job which is calling these three jobs in parallel executor. 

Thanks and Regards

For https://ci.jenkins.io we're using Multibranch Pipelines very heavily and I
*believe* that this was putting heavy pressure on the PermGen space in JDK7 and
causing some issues for us.

My solution, as suggested by a few others, was to simply upgrade to JDK8 wihch
has a number of improvements in handling objects which previously were stored
in this PermGen space. I wrote about that here:
http://unethicalblogger.com/2016/10/03/dropin-containerized-jenkins-master.html


If that isn't an option, making the PermGen space much higher might help, but I
*think* that JDK7 simply doesn't clean up the PermGen space properly so you
might still see "leaks."

This jdk upgrade is mainly for application code compilation or Jenkins compilation.
