We should provide documentation on how to debug a crashed or 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
- 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
