Symptoms

Merged may core on startup of tmm and/or bcm56xxd due to temporarily invalid statistics published by those services.

Impact

There is no impact to the system or the statistics. The invalid statistics are cleaned up automatically, and merged recovers successfully on its own.

Conditions

The core is seen rarely on startup of tmm and/or bcm56xxd, which can happen during a system startup from an upgrade or reboot, execution of the 'bigstart restart' command, or a re-license event. The exact conditions that cause the core on startup of these services are unknown.

Workaround

No mitigation is required, as the system recovers automatically.

Fix Information
