             Summary: AcitveMQ stop responding when OS running out of free disk space
                 Key: AMQ-4434
                 URL: https://issues.apache.org/jira/browse/AMQ-4434
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
    Affects Versions: 5.8.0
         Environment: RHEL 6.4 x64 bit
            Reporter: Andriy Kalashnykov


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.
