[jira] Updated: (AMQ-2595) NFS problems can cause broker to hang on
shutdown requiring a hard kill
[ https://issues.apache.org/jira/browse/AMQ-2595?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dejan Bosanac updated AMQ-2595:

Fix Version/s: (was: 5.4.2)
5.5.0
> NFS problems can cause broker to hang on shutdown requiring a hard kill
> ------------------------------------------------------------------------

> When the ActiveMQ data directory exists on a NFS mounted volume and that volume experiences some type of failure, it can cause the broker to hang and only a manual kill will shut it down. Below is a sequence of errors demonstrating this:

> {code}
> In this case, a problem occurred with the NFS mount point where the data directory lives which resulted in the I/O error. After sending a ctrl-c to shut down the broker, it would not shut down on it's own so it had to be killed. Only then could failover take place allowing another broker could grab the lock.
> Given that the broker cannot recover from such a problem, it should probably force itself to shut down so that failover can take place. Also, such a failure should be a FATAL and not an ERROR in the logging.
