Subject [jira] [Commented] (AMQ-4573) AMQ not starting when using default heart beat
Date Thu, 06 Jun 2013 21:42:20 GMT

    [ https://issues.apache.org/jira/browse/AMQ-4573?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13677546#comment-13677546
] 

Timothy Bish commented on AMQ-4573:
-----------------------------------

The default heart beat setting has no relationship with the store and this error, you are
most likely encountering an issue due to the state of your store.  Many issues are fixed in
the SNAPSHOT builds.
