I actually wrote a blog on how I keep an eye on JVM garbage collecting at http://gitsense.github.io/blog/realtime-process-monitoring.html http://gitsense.github.io/blog/realtime-process-monitoring.h... My indexers are designed to automatically shutdown, if they are spending more than 30% of their time doing garbage collecting, in the last 10 minutes. If they shutdown on purpose, my background Perl script will restart them. However, if they shutdown X number of times in a row, my Perl script won't restart them. Multiple consecutive shutdowns, usually means I'm pushing the system too hard and I'll need to tweak my indexers thread settings.
