SOS Messages
An SOS message is a system message sent out by the DMS switch due to a restart.
The following types of restarts cause the switch to send out an
SOS message:
- COLD Restart
- WARM Restart
- SOS Reload
The TSM reacts to SOS messages differently from normal events.
If the TSM receives an SOS message while parsing an event, the TSM creates
an extra element: $RestartLine. This element contains the
SOS message and is added to the list of elements created for the event. If
the TSM receives an SOS message during login, the TSM sends out a Switch is
being rebooted TSMWatch message. The TSM then disconnects and reconnects using
the backoff strategy.
