Problem Description


I JUST bought this server, it is modded and all of the files are in the correct location - just a few hours ago I made the server public to my group of 15 friends and only about 4 joined off the bat… the server ran just find for about an hour and then suddenly crashed. After trying to reopen it multiple times it crashed upon someone taking a step over 1 block… I changed the memory heap limit and it started working again for ab 20 minutes… and crashed once again. I tried to change the limit more to no avail - I watched the console and it was saying that the server may be overloaded and it was ticks behind and crashed again.

Reproduction Steps

  • changed Memory Limit (MB) Java Heap Size to lower amount/higher amount
  • restarted the server and gave it time to load before having someone join… it crashed shortly after
  • checked the files and console information live… nothing was wrong except for the console saying “Can’t Keep up! Is the server overloaded? Running ----ms or ----ticks behind”

Means the CPU can’t keep up for the mods you’re trying to run or you could be generating too many chunks all at once (MC is mostly singlethreaded, causing issues like this. For more insight use the Spark profiler mod to see what’s using the most CPU time. If you’re with Hostinger and think it’s a hardware issue, contact them.
