Just so you know, my husband an I encountered the exact same problem on our small server. I had tried a few days ago to put down a builder block, which caused the server to crash completely. I removed it using MCEdit, and I only deleted that single block. Next thing we know, the server is lagging like crazy, and when we mined a little bit underneath the area where the builder block HAD been, we found that there were hundreds of mining turtles lined up underground that had never been placed there before. After trying a few different things, we came up with an easy fix: Remove the ComputerCraft mod from the mod folder of your server files. Restart your server without the mod. This should eliminate all of the turtles. Close your server, put the ComputerCraft folder back into your mods folder, and start your server again. Voila! No more turtles, no more lag. Also, no more MCEdit. What a pain. TL;DR: This guy isn't crazy, MCEdit really can put random mining turtles in your Tekkit world.
