CA-CCI address space CCITCPGW yields:
12:03:37 BPXF024I (SYSLOGD) May 15 16:03:37 MVSASYS1 TRMD.TCPIPÝ396¨: EZZ8662I

The format of the PROTOCOL statement is: PROTOCOL(protocol,netparm,retry,sysid,maxru,start/stop)
In this case, the CAICCI PROTOCOL statement was coded as:
PROTOCOL(TCPIPGW,7102,20,ASYSCCI) which sets the retry time to 20 minutes causing a 20 minute delay for the shutdown of CCITCPGW.
This value was detrimental to processing, and caused the "constrained" message.
The default retry time should be 2 minutes, and the "delay" time would be 2 minutes as well. This will prevent the "constrained" message while dealing with unexpected misconfigurations
To accomplish the above, adjust the CAICCI protocol parm to:
