Recently I migrated from Nexus 2 to Nexus 3.44.0-01, running directly on a Ubuntu 22.04 VM, not in a docker container.
Everything went fine for 2 days, yesterday I tried to fix a warning about maximum file descriptors by adding
nexus - nofile 65536 to /etc/security/limits.conf
and restarting the nexus service.
Now it doesn't start anymore, startup log ends with:

First i thought it was a database problem and followed the steps mentionend https://stackoverflow.com/questions/51776568/sonotype-nexus-repository-orientdb-cant-connect-to-database?noredirect=1&lq=1 here, but it didn't change anything.
I also noticed some maven-related exceptions like these:

earlier in the log, but I don't suspect they have something to do with nexus not starting?
I just downloaded nexus-3.45.0-01 and somehow it starts up again, so it seems the old installation was somehow corrupted.
