Too offensive messaging in DEBUG: running class-c scheduler batch

Hi,
when running in debug my eyes and head becomes overhelmed by the message:

Dec 29 23:54:31 LoRa loraserver[418]: time=“2017-12-29T23:54:31+01:00” level=debug msg=“running class-c scheduler batch”

running class-c scheduler batch is

Can I disable it somehow by the configuration without disabling other debug messages?..

Thanks.
