Thats weird, i check on settings how much i have of ram and it appear i have 8 gb, at the wiki said something about putting more ram into the game (?), im gonna try that for now and see what happens

At a glance, it seems like you might not have sufficient ram?   The console log shows that you only have ~70mb available out of 3gb max, while Zomboid lists 8gb in the system requirements.

It’d be located in the steamapps/common/ProjectZomboid folder, but only would appear for certain types of crash.

I am using a headless VPS running Ubuntu Server 26.04 which I planned to use to host a zomboid server for my friends. I firstly tried configuring the stable version which worked flawlessly, untilI tried b42 and no matter what I tried it would always break.   What I did: Following the wiki steps (including Magnet AFK's guide as reference); Running start-server.sh after installing everything; Once hosting the server would forcefully shut down after multiple errors.   What I also tried: Downloading and running the pz dedicated server on my PC which does get steam running but my router has upnp off. Redoing the installation process multiple times making sure I didn't miss anything (including reinstalling PZ dedicated server). As ideas for the cause of such errors could be SLF4J not working as expected, nevertheless I don't know how I can solve this myself. The 14-55 log is from the PC, the 15-49 log is from the VPS.
