Subject [jira] Commented: (AMQCPP-189) the message producer core dump during sending lots of messages
Date Thu, 31 Jul 2008 11:08:00 GMT

    [ https://issues.apache.org/activemq/browse/AMQCPP-189?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=44653#action_44653
] 

Timothy Bish commented on AMQCPP-189:
-------------------------------------

This isn't really a bug, currently we do not support Openwire V3 so we cannot respond to flow
control messages from the broker.  What's happening is your broker is running out of memory
and eventually doesn't respond to a new message being produced which causes the cpp client
to fail.  There's not much that can be done on our side until the support of V3 is added to
ActiveMQ-CPP.
