> LevelDB on NFS creats .nfs files
> --------------------------------
>
> Key: AMQ-5430
> URL: https://issues.apache.org/jira/browse/AMQ-5430
> Project: ActiveMQ
> Issue Type: Bug
> Components: activemq-leveldb-store, Broker
> Affects Versions: 5.10.0
> Reporter: Anuj Khandelwal
> Priority: Critical
>
> We are currently testing levelDB on NFS.
> leveldb creates .log files in leveldb directory to store actual message/data
> and this files rotates after 100MB size. These .log files gets deleted when
> all the messages are consumed from a particular file.
> Issue: After all the messages are consumed I can see that files are getting
> deleted but internally they are creating .nfs files of same size.
> we have to restart the process to delete those .nfs files.
> From my understanding: It seems that the LevelDB store keeps the old logfiles
> open after they were deleted.
> Below is the snapshot of files:
