It make sense to run out of PermGen space after upgrading.  Presumably, the 
upgrade has more classes to load, which fills up your PermGen space.

If you're using HotSpot 1.6, I believe (but could be wrong) that the option is 
-XX:MaxPermSize={size}.  For 1.6, the default size is 64m, so you may want to 
try -XX:MaxPermSize=128m.

I've seen the same Content Encoding Error you mention below, but I don't know 
what it means or if it's related to the PermGen space thing.

This was working with the same amount of PermGen Space yesterday BEFORE the 
upgrade.

jenkins JVM options:

/usr/bin/daemon --name=jenkins --inherit --env=JENKINS_HOME=/var/lib/jenkins 
--output=/var/log/jenkins/jenkins.log --pidfile=/var/run/jenkins/jenkins.pid -- 
/usr/bin/java -Xmx2048m -jar /usr/share/jenkins/jenkins.war 
--webroot=/var/cache/jenkins/war --httpPort=9000 --ajp13Port=-1

/usr/bin/java -Xmx2048m -jar /usr/share/jenkins/jenkins.war 
--webroot=/var/cache/jenkins/war --httpPort=9000 --ajp13Port=-1
Thiis is what i see when i do ps -ef | grep java


Java version:

java version "1.6.0_35"
Java(TM) SE Runtime Environment (build 1.6.0_35-b10)
Java HotSpot(TM) 64-Bit Server VM (build 20.10-b01, mixed mode)


after i let the Jenkins stay initially at the main , i get the following error 
in by browser ( this is in addition to the CPU being pegged 100% )

Content Encoding Error

          The page you are trying to view cannot be shown because it uses an 
invalid or unsupported form of compression.
  Please contact the website owners to inform them of this problem.

Some build's ago in 2009, i saw someone complain about the exact coding error, 
and it was a plugin issue that Kohsuke fixed in the release plugin.

Thanks,
-Kamal.

If you're running out of PermGen space, your problem is with your JVM.  Your 
CPU may be getting pegged because your JVM is desperately garbage collecting to 
get every last byte of storage left, but I could be wrong.  Basically, you're 
going to have to tell the JVM running your Jenkins instance to give you more 
PermGen space.

Find out (if you don't already know) which application server you're running 
Jenkins with (if you're launching it like "java -jar Jenkins.war", you're using 
the onboard WinStone app server), and which JVM you're running that server in.  
You'll have to determine how much PermGen space you're allocating (likely the 
default that your JVM gives) and how to tell the JVM running your App server to 
give it more.  Again, if you're launching Jenkins as a plain Java app and using 
WinStone, you can add the PermGen space arguments right to the Java command 
line.

Subject: java.lang.OutOfMemoryError: PermGen space after upgrade to 1.500

Hi,
After i upgraded Jenkins to 1.500 on ubuntu 12.04 host. I am getting
java.lang.OutOfMemoryError: PermGen space
After i click any link on Jenkins page, the CPU gets pegged 100%


This also happens when i let the page stay there and not click on anything.

Anyone found a resolution for this?
Thanks,
-Kamal.
