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.
