I am able to explore my server multiplayer world just fine for several minutes and then all the sudden it'll hang and crash. The same thing happens when I use a mod to try and pregen the world. Each seed I try seems to have a specific spot where the server just can't load a chunk and then it'll just always crash when I get close to it.

 

The above error is what I see in the console before the server watchdog kicks in. The attached crash report is what is given but I don't know that it's helpful because it seems to just talk about the watchdog event.

 

I have been testing out the mods you see in the crash report and everything works great with the exception of this occasional error. I am ready to start using the modpack but now I am afraid to explore the world :(

The amount of data loading exceptions in this log is disgusting.

Remove Engineers Tools, start the server, stop the server, and provide debug.log again

This is my Forum Signature, I am currently attempting to transform it into a small guide for fixing easier issues using spoiler blocks to keep things tidy.

 

As the most common issue I feel I should put this outside the main bulk:

The only official source for Forge is https://files.minecraftforge.net, and the only site I trust for getting mods is CurseForge.

If you use any site other than these, please take a look at the StopModReposts project and install their browser extension, I would also advise running a virus scan.

 

For players asking for assistance with Forge please expand the spoiler below and read the appropriate section(s) in its/their entirety.

I tried without Dungeon Crawl and then also removed others like Ice and Fire / Quark since they also do their own structure generation. It still ends up crashing. I've given up :shrug:

I've finally been able to get the world to stop crashing while loading chunks. One of the crashes gave me coordinates (see below) and with WorldEdit using the //distr command it was able to tell me that Sky Stone blocks were around there. So, I disabled meteorites (which is what Sky Stone is used for) in the applied energistics config file and re-loaded the same seed without those meteorites.

 

I'm not sure if it was clashing with another generation mod or why meteorites were the problem but I'm glad I have a workaround. I'll probably submit something to AE to see if they can see what's going on.

 

Example message related to coordinates for documentation purposes:
