"JVM is terminating. Shutting down Winstone"

[adriaanm]

This job just stopped with no apparent reason.

The log on jenkins-master says:

Feb 16 18:05:07 ip-172-31-2-59 [jenkins]: INFO: JVM is terminating. Shutting down Winstone

OOM ?

We already run under

cd /var/lib/jenkins
touch jenkins.start
exec chpst -u jenkins -U jenkins \
  env HOME=/var/lib/jenkins \
  JENKINS_HOME=/var/lib/jenkins \
  java -server -Xmx4G -XX:MaxPermSize=512M -XX:+HeapDumpOnOutOfMemoryError -jar jenkins.war \
  --httpPort=8080 \
  --httpListenAddress=127.0.0.1 \

and no hprof memory dumps were found. CPU usage was much higher than usual according to EC2 monitoring, but that's all I have...

Maybe it's terminated from a browser console due to a javascript bug. Or a Jenkins virus!

That message is logged in a JVM shutdown hook

If we keep seeing this, we could start that JVM with a custom java agent that logs a stack trace when System.exit is called. I can't think of a more straight forward way to diagnose this.

Closing because we haven't seen this since.
