If you were just inserting a lot of data fast, it may be that background compaction was unable to keep up with the insertion rate. Simply leaving the node(s) for a while after the insert storm will let it catch up with compaction. (At least this was the behavior for me on a recent trunk.) -- / Peter Schuller
