Systems Management

I am supporting a small to moderately-sized K1000 deployment.  I have an increasing number of users reporting mysterious pop-ups.  When I get screenshots, I see it is CABARC.EXE in the prompt title, so I assume that is the running process.  This appears to be during patching schedules, and when LMDetect.exe and/or KDeploy.exe and other related K1000 executables are running.  It appears to be overflowing the log limit for these Windows Update files.

I know I can delete them, but are their knobs related to log verbosity I can test to make this stop?  I am not sure how it could be happening as K1000 and vanilla Windows Updates (no WSUS) GPO settings are all these computers have.
