Server stops working randomly after hour ish.

So its like servers time just stops, players don't get kicked the server just stops. First times there was nothing in console and one time we got this:

FAILED TO GENERATE WORLD POSITION!!!!!
 
Any idea why? CPU and RAM shouldn't be an issue.

Try unloading all plugins and see if that makes a difference.

Ive had this problem, were you using a generated custom map?
