When MCP logging on a chassis is set to Enabled, Verbose, or Debug for Audit Logging, the system sends numerous messages to the var/log/audit log. This causes the log to fill, which might render the GUI inaccessible.
When the var/log/audit log is full, the GUI might become inaccessible.
This occurs on chassis only when the Audit Logging option MCP is set to Enabled, Verbose, or Debug.
The workaround is to specify Disabled for the MCP option in Audit Logging (available under the System :: Logs).
The primary blade formerly sent a message to all secondaries every second telling them to change the primary selection time. (The actual timestamp is correct and is the same every second.) Over time, this might fill up the audit log. This no longer occurs, and the message is now sent only when the primary actually changes.
