A friend of mine is playing with mekanism on my server and sets up everything very large. Now the server regularly gets a stack overflow exception.

How can we avoid that? What is the error here? Looks like an endless loop (which causes the stackoverflow exception):

Description: Exception while updating neighbours

This does not only appear while chunkloaded, it also happens while he is online.

Same issue as #4096. Please search for already reported issues before reporting.

This just happened to me, here is the log. https://pastebin.com/0W2hPMvd
