[jboss-jira] [JBoss JIRA] Commented: (JBMESSAGING-1682) duplicate key value violates unique constraint "jbm_msg_pkey" exceptions in a clustered

[Howard Gao (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBMESSAGING-1682?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12475561#action_12475561 ] 

Howard Gao commented on JBMESSAGING-1682:
-----------------------------------------

Yes, the ID generation algorithm is dubious. The node id field, time field and counter field overlap each other, I believe it is not what it is intended.
It needs to modify the code a bit.
Thanks!
