Alex Petrov commented on CASSANDRA-12652:
-----------------------------------------

Wanted to give heads up that I've found the background / reason for this problem. I was right in that it was being caused by compaction, although it had two manifestations, one of which was like here and second one - segfaults on mmaped file release. Both problems were caused by the prematurely closed resource in 11990.
