Additional cleanup for VARY TCPIP,,SYSPLEX

When configured for SYSPLEXMONITOR a system may receive a "EZZ9675E SYSPLEX PROBLEM DETECTION CLEANUP HAS FAILED FOR
TCPIP" message, setting several flags (XFCVT_PDCFAIL_Event/XFPD_Partial_cleanup) which essentially marks TCPIP as a non-member of the TCPplex and requires a restart to recover. This situation may happen on a system which is experiencing high CPU condition or perhaps extremely high paging rates. The TIMERSEC parm offers some control over the interval before EZZ9675E is issued. The problem is that regardless of what this is set to, basically once EZZ9675E comes out it is non-recoverable save for a TCPIP restart. I'd like to see if some manner of recover-ability can be implement for this or similar messages which might set the "partial cleanup" flag.

Specifically, I'm wondering if a "FORCE" parameter can be implemented for the V TCPIP,,SYSPLEX,JOINGROUP/LEAVEGROUP parameters which could possibly clean up the XFCVT_PDCFAIL_Event/XFPD_Partial_cleanup or similar flags. Perhaps this wouldn't be allowed for all flavors of condition flags, but maybe certain ones would be allowed to recover from.

    A FORCE command would essentially be a TCP/IP recycle. There is a technote describing why a TCP/IP recycle is needed. https://www.ibm.com/support/pages/why-zos-tcpip-issuing-message-ezz9675e-and-how-should-we-respond-it
