Sporadic entries in KIWI ErrorLog

While browsing the KIWI ErrorLog I noticed these lines pop up but at apparently random times. Sometimes multiple times a day, sometimes not for days at a time. Can't seem to find any reference to them. It's not that the messages are cryptic in and of themselves, but why do they show up in the Error log at such random intervals. Is it a resources utilization event that triggers these actions?

Just curious if anyone else has noticed this.

Thanks
