Bob Clary commented on COUCHDB-926:
-----------------------------------
While the situation in 1.0.2 is much improved over 1.0.1, there are still cases
where the deleted files are not released and are still held open by beam. I
don't have specific steps to reproduce however it appears to be related to
heavy load with couchdb crashing after compacting views and leaving the
original file open.

> Project: CouchDB
> Issue Type: Bug
> Components: Database Core
> Affects Versions: 1.0.1
> Environment: Ubuntu 9.04/10.4
> Reporter: Russell van der Walt

>
> 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.
