Claus Ibsen commented on AMQ-4434:
----------------------------------

There is some disk space left check in AMQ 5.9 on startup. You get a WARN logging if the broker does not have as much free space as configured to allow to use.

> AcitveMQ stop responding when OS running out of free disk space.
> Steps to reproduce: run ActiveMQ with almost no disk space left, use hdd to the point that there is no more left. 
> This behavior directly affect HA: in my case, i have four instances of ActiveMQ on different physical servers and ActiveMQ configured to share Oracle DB. First server became master worked for a while and went down, then second server (the one with little disk space left) became a master and worked for a while, than it became unresponsive and all AcitveMQ cluster was unaccessible. 
> I belive it's due the fact that on the box with little space ActiveMQ was still running and perhaps preventing DB connection to be release for other servers to use.  
> Suggestion: check disk space on start and periodically after start, once disk space is low on none left - gracefully exit.
> Regards.
