Claus Ibsen updated AMQ-5430:
-----------------------------
    Priority: Major  (was: Critical)

> 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
> 
> 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:  amqtest@kepler19.nyc:/u/amqtest/dev/leveldb> ls -a
