SCN-1001

Message SCN queue overflow for process <daemon name>.

Message Type FFDC | LOG

Severity CRITICAL

Probable Cause Indicates that an attempt to write a state change notification (SCN) message to a specific queue has

failed because the SCN queue for the specified daemon is full. This may be caused by the daemon

hanging or the system being busy.

The following are some valid values for the daemon name:

• fabricd

• asd

• evmd

• fcpd

• webd

• msd

• nsd

• psd

• snmpd

• zoned

• fspfd

Recommended

Action

If this message is caused by the system being busy, the condition is temporary.

If this message is caused by a hung daemon, the software watchdog will cause the daemon to dump the

core and reboot the switch. In this case, execute the supportSave command to send the core files using

FTP to a secure server location.

If the message persists, execute the supportFtp command (as needed) to set up automatic FTP

transfers; then execute the supportSave command and contact your switch service provider.
