Subject [jira] [Commented] (QPID-3286) cluster node went down
Date Mon, 06 Jun 2011 13:23:58 GMT

    [ https://issues.apache.org/jira/browse/QPID-3286?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13044835#comment-13044835
] 

Alan Conway commented on QPID-3286:
-----------------------------------

Presently you can't auto-expand a store while the broker is running.

However a good solution is to set a queue limit policy on you're queues with a limit that
is lower than the size of your store. Policy exceptions are synchronized across the broker
so if you exceed the limit on a queue, the sender will receive an exception and the cluster
will continue as normal.

Any time you add a node to the cluster, it will synchronize with the other members when it
joins.

any issue for few hours or sometimes one or two day. But one  node went down after some time
with following error.
