hardcopy console lnx02

We run a lot of linux vms on our VMware vCenter 7.0.3, different Debians,
RedHats plus openSUSE Tumbleweed and Leap 15.3 without difficulties for years
now.

The next day after I updated some VMs from Leap 15.3 to 15.4 I realized that
they were frozen over night. I was not able to find the point when that
happened, could only grab a last hardcopy from the console. Even journalctl did
not show useful information for me. One of them "lnx02" carries a Tomcat based
application, the other one "lnx99" an Apache with three vhosts. Both are rarely
used, lnx02 because it is a test system and lnx99 because it is a clone master.
Users have not been on the systems during the freezes.
