Useful information to include:

• Minecraft version: 1.14.4
• CC: Tweaked version: 1.86.0
• Forge Version: 28.1.107
• Detailed reproduction steps: It's totally random I think or not.. it happens alot or it happens once in awhile i don't know how to exactly re-produce it. But looking at the crash report and then the stacktraces i've finally found a mod there. The only one in my roughly 14 Crash reports, they all have "computercraft" in them. Do CTRL + F and search for "computer" and you'll find the message below in all the crash reports i've listed. Any ideas?

This crash occurs when the server has lagged so much, Minecraft gives up and just kills it. It's most likely unrelated to ComputerCraft - we generally have very little impact on tick time.

Just a couple of other notes:

• You can set max-tick-time=-1 in your server.properties to disable this error. You probably don't want to though, as it means you have a 1m lag spike.

• You might want to install something like spark or Lag Goggles in order to track down what's actually causing this lag.
