https://quickview.cloudapps.cisco.com/q ... CSCuz57493CSCuz57493High CPU observed in punjectrx fed-ots-main thread
Symptom:
High CPU utilization due to FED and punjectrx. These are some possible processes, please have TAC confirm this defect as there could be multiple reasons why this occurs.
High Processes are likely to be one of the following:
FED/fed-ots-main
FED/Punject Rx
FED/XCVR
FED/XCVRPoll
stack-mgr/Replenish OOB
stack-mgr/OOBnd RX
Conditions:
This can be easily seen in the switches/stacks that has long uptime (several months).
Workaround:
When the problem is happening NONE of the following options work:
- CPP (Control-Plane Policing)
- Storm control
- This problem can be confirmed by checking CPU usage from kernel perspective (Only TAC can check the kernel)
Reload the device to resolve the issue until code upgrade to pick up permanent fix
If this is a stack of multiple switches, a 'redundancy force-switchover' will not necessarily clear this.
Further Problem Description:
This can be confirmed by TAC without any impact to the switch.
