Description

When couch compacts a database, file descriptors of the deleted files are left open, causing the freed disk space to not be released to the system. With regular compaction, the system eventually runs out of disk space.

There is a conversation thread in the user mailing list titled "Couch not releasing deleted files" that gives more insight into the problem, but I have been unable to find a bug report for it, so please accept my apologies if this has already been dealt with.
