Cause:

The error code "-11 (Operation Failed)" is due to exhaustion of the stats counters related to the MPLS route entry from the dedicated pool of counters.

 

Solution:

These log messages are related to the stat counters. They do not have any impact on service and can be safely ignored.

To suppress repetitive non-impacting messages, refer to KB9382 - How to prevent certain syslog messages from being written to the log file
