Regular Server crashes

Modpack Version

1.6.1

Describe your issue.

I'm hosting an unmodified version of the modpack and we experience regular crashes. I have a hard time reading the crash log. Hopefully you can help me. We can't identify any source for the crashes at the moment, they seem random. I have checked the opened trakers but none of the situations seem to apply to us.

I have the same problem.

[ThaddMonteiro]

We have the same issue on our server. It occurs whenever one players base is unloaded. We removed all mekanism items from his base and that seemed to fix the problem for a while however the issue has begun to reoccur. Not exactly sure what is causing it.

It varies from watchdog errors to exception in tick loop and exception ticking world being the most common. Force loading the chunks seems to work, eventually it stops working and the chunks need to be unloaded and re-force loaded.

For more information, the base is making use of AE2 (+ Extended AE) Ars, Acutally Additions and Powah

There are claims the concurrent issue may be caused by ars energistique. if you can, would you be able to backup the world and test without that mod? (also up your max-tick-time to 240000 if you havent yet)

[ThaddMonteiro]

Removing the ars energistics mod did not work. The max tick time has already been increased. I will be attempting a few other fixes today and will update on any progress made.

Thanks for the troubleshooting you've done. I will update if one of the solution works or if I get a better idea of what's happening

[ThaddMonteiro]

Issue has been solved. If the chunk is unloaded while source is being transferred it causing the ticking world error.

Mods being used: Ars

Travel locations Arg Sourcelink -> Depositor Relay -> Source Jar -> Collector Relay -> Splitter Relay (x2-5 depending on path) to source jar

When the particles of traveling source are visible and the chunk is unloaded, the server crashes. If all source jars from “battery” are drained and no more source transfer is occurring the chunks can be unloaded no problem.
