Damien Katz closed COUCHDB-78.
------------------------------
Resolution: Fixed
Fix Version/s: 0.8
Assignee: Damien Katz
Problem was couchdb failing to close file handles during compaction reattempts.
Fixed in revision 667188.
Note, it is not a good idea to attempt compaction on a database is near full
capacity for its write load. The problem is the compaction process may never
catch up with the writes if they never let up, and eventually it will run out
of disk space.
Compaction should be attempted when the write load is less than full capacity.
Read load won't affect its ability to complete however.

> Not sure if this is a CouchDB or Erlang bug or both. Please, forward to
> Erland team if appropriate.
> What happened:
> I've started several thousands of atomic inserts with modified sample php
> script from http://wiki.apache.org/couchdb/GettingStartedWithPhp
> In the middle of insert loop I initiated database compact from
> localhost:5984/_utils interface.
> Several thousands of inserts later CouchDB dumped the following error and
> terminated:
