Error description

ABENDS0C4 occurs in a nodeagent when using local communications
from a nodeagent to an application server that is being stopped.
The callback stack that generated for the NA TCB that had the
0C4 looked like this:
CF_Local_Connection::clientSend(LocalComm_IOV_Header*,int,in
            -04850B48              *PATHNAM

* RECOMMENDATION:                                              *
****************************************************************
When a application server is being stopped there is a timing
window in which the private storage for the PC routine has
been removed but the PC entry in the LXLIST has not. This can
result in an Abend S0C4 if the nodeagent attempts to use local
communucations to access the application server as it is
stopping.

Problem conclusion

During controller task level termination processing an LXFRE
was added to remove the PC routine from the LXLIST to prevent
access to the PC routine, whose private storage has been
removed, during controller termination.
