Buildcraft Crash in Tekkit 2.0

[Arin³]

We're having the same bug from Tekkit Beta, in which the use of Buildcraft pipes causes the server to crash and the map to corrupt itself. There are various fixes but I can't find anything that will permanently fix the issue, except disabling the use of pipes on my server. I don't know if it is an Issue in tekkit; I think it is in BC in general, but I want to post it here just in case somebody here does have a fix. Here is the log:

I know how to fix the map without resetting it, as a helpful link was posted on technicpack.net, but I'd like to keep using BuildCraft pipes in SMP and would like to know if there is a permanent fix because it is getting really annoying. I have found other threads about this but It doesn't seem to be in the known bugs list.

does no one have a fix for this?

[gcity306]

Did placed teleportpipes next to other kinds of pipes? Give more information how you produced this...

[J0P5]

We don't actually know, the server just stopped working and we have a lot of people on the server. Impossible to tell who or what caused it. (we fixed it with a rollback).

Although I do assume teleportation pipes were not the cause of this, as I don't recall anyone using them (yet), nor are they in the error report. It seems that it's the waterproof pipes but I can't tell for sure.

[Mastergalen]

I got the same problem and have no idea what's causing it.

We had a servercrash related to this. In the end, removing BC engines from the affected area sorted our issues atleast. This seems to happend more often now that the client have updated, how it affects the server, i dont know

Same issue, its related to where one of my players is located and generates the error when he spawns near it.

Any advice on how to fix?

I am guessing disable BC, load the server, delete the offending item, and block it from use (if possible) and then restart the server with BC enabled.

Only a small issue that I don't know which item is causing it.

help anyone?

[Mc_Duff]

Looks like it is relating to pipes. Do we know if any pipes have been removed from 2.0 to 2.1.

I am trying to work out how to edit the bag.dat file that the offending item is in. if not i'll have to remove it, completely.
