> Transaction logs are leaking
> ----------------------------
>
> Key: SOLR-4831
> URL: https://issues.apache.org/jira/browse/SOLR-4831
> Project: Solr
> Issue Type: Bug
> Reporter: Steven Bower
>
> We have a system in which a client is sending 1 record at a time (via REST)
> followed by a commit. This has produced ~65k tlog files and the JVM has run
> out of file descriptors... I grabbed a heap dump from the JVM and I can see
> ~52k "unreachable" FileDescriptors... This leads me to believe that the
> TransactionLog is not properly closing all of it's files before getting rid
> of the object...
> I've verified with lsof that indeed there are ~60k tlog files that are open
> currently..
> This is Solr 4.3.0
