[jira] [Commented] (COUCHDB-1129) file descriptors sometimes not
closed after compaction
[ https://issues.apache.org/jira/browse/COUCHDB-1129?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13127279#comment-13127279 ]
Dan Everton commented on COUCHDB-1129:
--------------------------------------
We're still seeing this issue with CouchDB 1.1.0. The database isn't under particularly heavy write load but every single compaction leaks file handles. This is on R14B with the default CouchDB command line settings.

> Key: COUCHDB-1129
> URL: https://issues.apache.org/jira/browse/COUCHDB-1129
> Project: CouchDB
> Issue Type: Bug
> Components: Database Core
> Affects Versions: 1.0.2
> Reporter: Randall Leeds
> Fix For: 1.2
>
>
> It seems there are still cases where file descriptors are not released upon compaction finishing.
> When I asked on IRC rnewson confirmed he'd seen the behavior also and the last comment on 926 also suggests there are still times where this occurs.
> Someone needs to take a careful eye to any race conditions we might have between opening the file and subscribing to the compaction notification.
