I did my own search and could not find anything, but that doesn't mean it is not a known problem. Either way, I suggest opening a PMR with IBM Communications Server TCP/IP support. If it is a known problem, they will point you to a fix. If it is not, they will direct you on what type of traces, dumps, or other documentation they need to diagnose and fix the problem. The good news is that since the problem is repeatable, you can get IBM the documentation they will need. Hopefully you can do this on a test LPAR.
