Jenkins Crashing

[Harlan Barnes]

I'm having an issue where jenkins/java crashing regularly and often. It had been working fine for a long while and I had to restart the VM recently. It then started failing over and over again. I've rebuilt a new Centos6 image from scratch, re-installed, re-added each plugin until I got it running again. It ran for 4-5 days and then started crashing again. I've captured the error below ... does anyone have any ideas where I could look?

I've tried ...

- Rebuilding the VM from scratch (as described)

- Swapping JVMs: OpenJDK 1.7, OpenJDK 1.6, Sun JDK 1.7

Current details ... with command line info ...

/etc/alternatives/java -Djava.awt.headless=true -Xms1024m -Xmx1024m -XX:MaxPermSize=512m -XX:+CMSClassUnloadingEnabled -XX:+UseConcMarkSweepGC -DJENKINS_HOME=/var/lib/jenkins -jar /usr/lib/jenkins/jenkins.war --logfile=/var/log/jenkins/jenkins.log --webroot=/var/cache/jenkins/war --httpPort=8080 --ajp13Port=8009 --debug=9 --handlerCountMax=100 --handlerCountMaxIdle=20

[root@jenkins jenkins]# java -version

java version "1.7.0_25"

OpenJDK Runtime Environment (rhel-2.3.10.4.el6_4-x86_64)

OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)

[root@jenkins jenkins]# cat /etc/redhat-release 

CentOS release 6.3 (Final)

And the error ...
