Príčina


IPC-5023 messages causing Audit Log to wrap and switch instability.

Description:
Any switch without GE ports is susceptible to this defect.  It may go as far as triggering a kernel panic; alternatively, it may simply be that the Audit log wraps in record time.

From the logs:

Riešenie

It is a software defect so it should not be necessary to replace the hardware.
There is no work workaround for this issue as of now. The fix for the defect is not in 9.x yet, but should be in a future FOS release.
