Anything recorded in the logs?#show logging

Nothing that I can tie to this. This message is something I've seen on other switches that we have but I think it is no related:
Aug 24 12:59:30 %S3048-ON:1 %KERN-6-INT: CP Mgmt port receiving excessive traffic; will be rate controlled

I don't see any errors or discards on the other side.

Currently during time of very low data traffic and discarded frames increase still:
