Restarting a nodeagent with security enabled and its
Application
Server running, results in a failure to reconnect using the IPC
connector. Messages in the logs:

Problem conclusion

Corrected the logic that attempts the IPC connection to handle
the security enabled flag, correctly.

The fix for this APAR is currently targeted for inclusion in
fix packs 7.0.0.25, 8.0.0.4 and 8.5.0.1.  Please refer to the
