--- Comment #3 from Markus Zimmermann ---
This might be triggerd by a CronJob that is running on Monday 00:0x. Also, one
of the VMs of the server is down first. So this might be triggered by that VM
which is running some docker containers on LEAP 15 with no special packages.
Nontheless this takes down the whole hypervisor because it marks all RAIDs as
read-only bringing down the whole server with its VMs. I cannot Google anything
of the trace so I guess that this is again a kernel bug I am triggering that is
unique to SUSE.
