I have a three data node and one ingest node cluster.
I recently had a node fail during a snapshot and it brought down my entire stack which had been running well for almost 6 months. When I went to restart the failed node, I'm 'getting this error: "Unable to lock JVM Memory: error=12".
I have restarted nodes before and this issue has never occurred before therefore I don't believe this is a JVM locking issue but an issue with the failed snapshot having locked up something programmatically. Does anyone have any suggestions on how to correct this?
Thanks for your help.
