Go [link|http://www.ibm.com/support/us/|here]. Enter "Primer on Message Analysis" in the "Search Technical Support" box. Click on returned link #1. There's a lot of info there on troubleshooting - but I didn't see a direct answer to your question.
(I'd give you a direct link but it seems to address-ify the link so it probably wouldn't work.)
HTH a bit. Luck!
Cheers,
Scott.
