ACK.

If you can open a bug / support issue for SUSE that would be helpful. A link to
the bug report would also be helpful.

I don't know. I can't immediately think of a failure scenario where that could
happen but duplicate references to the same connection is going to trigger some
strange errors. It isn't a scenario that was in anyone's mind when the Tomcat
code was written. Depending on how those errors are handled, it might be able
to trigger the problem you are seeing. So I guess my position is that I
wouldn't rule it out but neither would I class it as a likely cause.

Understood. It is even more difficult for us to fix it. Please do add more
information as and when you have some but, for now, this issue is going to
remain in the NEEDINFO state until we have a test case we can use to reproduce
it.
