Issue/Introduction

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.

Resolution

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.
