It apparently all started when MTCSGATE issued a BSD-style socket call for socket 42. That was turned into IUCV SEND,TYPE=2WAY,TRGCLS=(socket call verb, 42). You can't tell from that message what the verb was (connect, send, receive, close, ...). When the stack tried to respond to the request (data arrived, connection complete, etc.), the IUCV REPLY (function 6) failed with CC=2, 'message not found'. That would tend to indicate a bizzare problem in the stack as the reply contains the same TRGCLS as the original request. CC=2 means that CP couldn't find an outstanding SEND with that TRGCLS that was waiting for a reply. If it is reproducible, a socket trace (remember to include Traceonly MTCSGATE Endtraceonly) would be edifying. If the stack really is replying to a non-existent message, contact the Support Center. If you like, feel free to submit an RCF about the missing message. Alan Altmark z/VM Development IBM Endicott
