When shutting down our z/VM system, we received these messages. Do they indicate a problem?
VMYIUT1183E Unexpected IUCV interrupt type 3 was received from TCPIP.
VMYIUT1352E Severing IUCV path 5 with TCPIP.
VMYRVS0239S Unexpected error 1183 from call to NUCIUSCL at 8FCE9B78.
No, these are normal messages as the system is being shutdown. You will receive these messages when TCP/IP goes away as long as VM:Operator is still running.
