Reclaim GcGem can hang
It's possible for the reclaim threads in the Reclaim GcGem to get stuck in an infinite loop during commit processing, causing them to consume CPU cycles but not never completing the commit. No further reclaim GC occurs and the session will ultimately cause a CR backlog.
Workaround
In versions affected by this bug, you will have to kill the Reclaim Gem (stopSession and stopReclaimGem will not work) and restart using startReclaimGem. It is still highly likely that the hang will occur again.
