The main symptom of this issue is clients being disconnected from smsMaster (on the SMS or System Management Server), including clients on the same machine itself.
On SLC and VWS nodes, there will be errors in the syslog (/var/adm/messages) from the various connecting processes.
Relevant errors in the syslog include:

Followed shortly by a reconnection:
