I suspect that this was fixed when you fixed the Networking Cable lag and a bunch of those crash bugs. Note that the description of the crash is "Watching server". I believe this means that the server was frozen and that is why it says Java.lang.Error - That code was just the last code that the server was running when it was killed.

I don't think that this was a problem with CCTweaks specifically, but if it happens again I will let you know.

Note, you actually left another stack trace which is a completely different bug inside of that block up there.

Has it not occurred again then? I think the issue here is a threading deadlock though where I don't know.

Ahh, thanks! I think I reported that one anyway, though it was a vanilla bug which I can't really do anything about (and IIRC has been fixed for 1.8).

inklit commented 7 years ago

I had a similar error (java.lang.Error) crash with description Watching server that threw a different stack trace related to a different mod that does not even use any advanced threading or anything that could cause issues, which is why I think that it is not necessarily the mods fault, however it does seem to be a threading deadlock. Can't really tell what caused the threading deadlock though, and the stacktrace is very misleading.

It has not happened again.

SquidDev commented 7 years ago

Right, I'm going to close this then. I don't think this is CCTweaks' fault but, if it occurs again. do create a new issue/post a comment here.
