COSD_UNEXPECTED_EXIT

June 18, 2016 by Marques Brownlee

COSD (class of service daemon process) waits for the event notifications and processes the events that it is registered for. There was an error during event handling initialization.

The COSD_UNEXPECTED_EXIT message is logged each time the class of service encounters an initialization error for an event sent to it.

When a COSD_UNEXPECTED_EXIT event occurs, a message similar to the following is reported:

cosd[3805]: COSD_UNEXPECTED_EXIT: Error: Invalid argument

This event will cause the cosd daemon to terminate immediately. It will then be restarted by JunOS. Therefore usually you will see the COSD_UNEXPECTED_EXIT message associated with the following syslog example entries:

init: class-of-service (PID 1061) exited with status=255 
init: class-of-service (PID 5323) started

The cause of the COSD_UNEXPECTED_EXIT event is due to an internal software failure occurring.

Examine the following output to help determine the cause of this message:

show log cosd
show log messages

Look for any related events that occurred at or just before the COSD_UNEXPECTED_EXIT message.
