From further testing it seems to start happening after build 2450 of Forge. There is a note that might be related in that build: That is just a hunch, but it does start happening with that build on to the current version. I rolled my server back to a build before that as a work around.

I have seen this same behavior, and am able to reproduce it by letting the chunk unload (like going to the nether or some other dimension) and then coming back. Still not able to determine what mod/mod combination is causing this though. EDIT: Seems the issue is with the Redstone Flux mod. No idea where to report the issue, since that mod does not have an issue tracker. Hopefully TeamCoFH responds on twitter. EDIT: Seems to happen even with no mods installed but simply forge.
