Subject [jira] [Commented] (CLOUDSTACK-7566) Many jobs getting stuck in pending state and cloud is unusable
Date Tue, 16 Sep 2014 22:28:34 GMT

    [ https://issues.apache.org/jira/browse/CLOUDSTACK-7566?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14136380#comment-14136380

Min Chen commented on CLOUDSTACK-7566:
--------------------------------------

Guard all potential unhandled exception in MessageBus gate.enter and gate.leave routine to
avoid potential lock holdup. Since each API will invoke messageBus to publish event, any potential
lock holdup will make jobs pending in the system and render cloud unusable.
