Jenkins Infrastructure : How to do a post-mortem analysis

Is it dead or is it unresponsive

Run ps -ef | grep wiki to see if the Tomcat JVM is still alive or not.

If it's alive...

  1. Get the heap statics with "sudo jmap -heap PID"
  2. Get the stack dump if you can. "sudo jstack -F PID". This can fail to respond.

If it's dead...

Look for hs_err_pid*.log files and capture it.
