I have just set up a paper server I have 1.5 GB of RAM (dedicated to the server) the server goes over within a minute and it crashes. I have no plugins and no players are joined am I doing something wrong?
Question Paper server uses too much RAM

Xmx controls the size of the heap, not the size of java itself; So, it's 100% normal that java uses more than the heap when memory is in use, 1.5G is lower than the recommended minimums these days of 2-3G of ram, so it's very little surprise that it will use the full heap either
If this is pterodactyl (or anything else using docker containers) I'd recommend you see this: https://developers.redhat.com/blog/2017/03/14/java-inside-docker
TLDR: java fails to see memory limits imposed by docker and only sees how much free memory the system has.
