Is there a way to reduce the amount of logging to syslog from worker nodes specifically these types of messages:
- Created slice
- Removed slice
- dependencies.scope: Scope has no PIDs. Refusing.
- Failed to get RecentStats(…) while determining the next housekeeping: unable to find data in memory cache
They are inundating syslog.
