      Description

      We should provide documentation on how to debug a crashed or frozen JVM.

      Frozen JVM:

      • Test TCP ports (port 8080) are responding
      • Check curl requests are working
      • Check logging still working, anything in logs
      • Run a jstack (and a top -H -n 1) 3-5 times with a minutes distance, dump the output to a file and submit it as a bug
      • Restart the JVM

      Crashed JVM:

      • Check the logs, grab the latest parts
      • If OOM grab the hprof file and contact PL to see if it can be used for analysis

      Etc. etc.
