I'm having a bad week - my ISR 4331 router has been flooding my syslog server with these messages non-stop and I can't seem to find why:

I've found this Parity Errors Troubleshooting Guide but I'm not seeing my exact error, I'm a little way about messing around in an area I'm unsure of. Hoping someone can point me in the right direction.
