Server crashing with "Connection interrupted"

My server keeps crashing when it hits the max slots (45/45) it doesn’t crash instantly, but this crash only happens when it’s full. It says “Connection interrupted” in the top left corner. It usually crashes within an hour of being full. Anyone know possible causes?

This is what happens in the console when this happens //////

server thread hitch warning: timer interval of 167 milliseconds
network thread hitch warning: timer interval of 153 milliseconds

Would the network thread hitch warning be caused by poor download/upload speeds?
