This is a cron job that runs every 10 minutes to check the status. The jobqueue is processed by systemd job which automatically restarts (with few seconds delay) when reaching limit of maximum jobs per one execution (1000) or on failure (I believe, didn't check). This sometimes causes false positives when check coincides with a restart.
It was added because sometimes (like after a reboot?) the jobqueue didn't run for days and that caused a lot of issues. Maybe checking the number of jobs in the queue instead and warn if it is high? Or age of oldest job?
