beegfs-meta went into high CPU lock-up again today, at 6:27:07 am, even with daily updates disabled. So apt-daily-upgrade is not directly related to the hangs.
It turns out though that there is other stuff scheduled around that time by daily cron:
25 6 * * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
It is still not clear what triggers the hangs, but it likely is related to a scheduled service, because of the consistency with which this happens at around 6:30am.
