Hi,

I am running into an issue wherein looks like we have a message sitting on a queue. It seems to block following messages on this queue. Any ideas,what kinda message could lead to such a situation. These are supposed to be simple XML messages.


thanks in advance.

Sounds like a poison message.

Time to troubleshoot the application to find out why it's choking.

That the application doesn't like the particular data in the message, and is constantly rolling it back to the input queue.

I couldn't begin to guess why - it would be entirely application specific.
