We are experiencing a problem running xmlBlaster 1.5.1. After running for several weeks, two nodes in our cluster start reporting the same types of errors:

It appears that there is a problem unsubscribing but I am unsure what the problem might be. Any thoughts or hints on how to proceed with debugging this problem?
