Pasted that error into Google, got some answers.

1. What version of Minecraft and which pack are you using, other people had this error in 1.42.
2. Using any of these machines in an auto processing chain? Some items macerate to more than 2 items, causing the buffer output to overfill and cause a crash.
3. Is the mod properly installed? Download it and replace the old copy to be 100% sure.
4. If the above steps don't work, make a backup, then use MCEdit to remove all advanced machines that come from that mod.

FTB beta pack a

from what I have gathered there was stuff going to an auto processing thing, but it was just iron. which shouldn't have broke anything.

yes its been properly installed, we have been playing on the server for about 2months with no problems.

and mcedit is out of the question. there are too many people with too many machines. will just restart the server if it comes down to something like that.
