Subject [jira] [Commented] (AMQCPP-465) Periodic access violation originating from Openwire::unmarshal
Date Thu, 21 Feb 2013 21:18:12 GMT

    [ https://issues.apache.org/jira/browse/AMQCPP-465?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13583558#comment-13583558
] 

Timothy Bish commented on AMQCPP-465:
-------------------------------------

My guess is that the issue is in TcpSocket.  I'm thinking that the socket is closed right
before an attempt by IOTransport to enter another blocking read and since the code closes
the socketHandle in an attempt unblock the readers that the recv call ends up using a bad
value in apr_socket_recv.

It appears only one occurred during termination. Attaching all 5 dumps.
