Description

As part of looking at MB-7824 I've found evidence of repeated compactor crashes.

Logs are available there.

Here's excerpt:

BTW, another node (.89) is having exactly same problem, just with different vbucket. And Abhinav mentioned that he did purge compaction. Which may be related or not.

Purge compaction is definitely related. Tracked this down. This will always happen on the second compaction after purge compact runs. http://review.couchbase.org/#/c/24885/ Fix here!
