RHEL-10-1 CPU/Memory unresponsive issues

[jelly]

On our smaller virtual machines 512MB RHEL-10-1 has been flaking out hard, seemingly due to memory issues:

               total        used        free      shared  buff/cache   available
Mem:             451         382           9           2          73          69
Swap:              0           0           0

testNoConnectionSettings fails on settling the CPU, the highest cpu usage is:

+ ps --no-headers -eo pcpu,pid,args | sort -k 1 -n -r | head -n1
22.1    1930 /usr/bin/python3 -s /bin/dnf needs-restarting --exclude-services

Interestingly sitting in the test "resolves" the issue so it is combination of a memory spike and dnf eating ram.

What causes dnf to run is unclear to me.
