We've encountered problem where compaction hangs and never completes.
After looking into it further, we found that the compaction scanner was stuck
in a infinite loop. See stack below.

Description:
We've encountered problem where compaction hangs and never completes.
After looking into it further, we found that the compaction scanner was stuck
in a infinite loop. See stack below.
