monitored from admin UI, could not find any clue at the time of failure.

heap usage varies from 5 gb to 12 gb . Initially it was 5 gb then increased
to 12 gb gradually and decreasing to 5 gb again. (may be because of garbage
collection)
10-12 GB maximum heap uses, allocated is 50 GB.

Need to analyze GC pause. Any suggestion how i can monitor resource usage
and GC pause effectively.
