Symptom

Repeating syslog messages: *Sep 15 14:52:39.716: %IOSXE_INFRA-6-PROCPATH_CLIENT_HOG: IOS shim client 'fman stats bipc' has taken 269 msec (runtime: 269 msec) to process a 'unknown' message

Conditions

NBAR enabled in running-config. This issue was observed on ASR1000 and ISR4000 series platforms.

Workaround

there are two workarounds available. 1. Disable asymmetric sockets : "(config) no ip nbar classification auto-learn top-asymmetric-socket" or 2. Workaround is to add log discriminator to the config to suppress the messages. conf t logging discriminator fman msg-body drops to process a 'unknown' message <<< if a message has ?process a 'unknown' message? in it's body, the message is dropped. logging buffered discriminator fman 409611 <<< note this command will clean up ?show log? output first logging host discriminator fman <<< filter the message from logging servers
