I have had a  similar problem, in several versions of tekkit.

I believe it is caused by having two different types of pipes (e.g. power and item) on the same frequency. make sure none of your pipes are set to zero anywhere else. If on a server then it is a very hard problem to overcome in my experience. In vasvadum's case, try clearing your cache then redownloading tekkit.

hope it helps,
