>                 URL: https://issues.apache.org/jira/browse/COUCHDB-808
>             Project: CouchDB
>          Issue Type: Bug
>          Components: Database Core
>    Affects Versions: 0.11
>            Reporter: Robert Newson
>
> Couchdb can make a .compact file when the volume is almost out of disk
> space and then crash before writing the header.
> If you then clean some space and try to compact again, it won't ever work.
> [Wed, 23 Jun 2010 16:11:59 GMT] [error] [emulator] Error in process
> <0.1976.0> with exit value:
> {{badmatch,no_valid_header},[{couch_db_updater,start_copy_compact,1}]}
> The presence of the invalid .compact file prevents it, and needs to be
> manually removed.
> Remedy: delete the .compact file if there is no valid header when _compact is called for the second time.
