>          Issue Type: Bug
>          Components: Openwire
>    Affects Versions: 2.1, 2.1.1, 2.1.2, 2.1.3
>         Environment: Linux 2.6.9-42.ELsmp #1 SMP Sat Aug 12 09:39:11 CDT 2006 i686 i686 i386 GNU/Linux

> Client setup is a JMS client sending messages to a C++ process with a timeout. Under heavy load the C++ process does not reply fast enough and the  java client gives-up.
> If the connection is dropped while the C++ is inside of OpenWireConnector::createProducer, an exception is thrown and the cleanup code causes a segv in:
> activemq/connector/openwire/OpenWireConnector.cpp:752
> (this is for CMS 2.1)
> reproduced for 2.1.3 as well. line 679 for 2.1.3
> Fix is pretty straightforward, do not delete the producerInfo twice. The first time it is done in producer should be sufficient. 
> Alternatively, I imagine setting producerInfo to 0 once it is deleted would avoid the crash as well.
