Will give a more detailed one later.
Noticed you are using ZFS. Where is your swap partition located?
On ZFS or?
Swap for dom0 is on a mdraid partition. Dom0 has 4GB RAM because it's
supposed to be used for making backups once I get to set that up and is
not swapping.
Update:
I updated the software, and the next morning the server was down again.
Yesterday, I pulled the disks and put it into another, identical HP Z800
which so far has been running without problems.
It didn't go down yet, and there is one peculiarity:

Why do I get a message that the link is up?
There is no message that the link went down. I checked another server
which is connected to the same switch, and the link on the other server
didn't go down and didn't come up, i. e. it was persistent.
6:45 is a suspicious time, but I haven't found any cron job which
might do something with the network card.
What might have happened here? Could this be some event which made the
other HP Z800 go down?
