Steps to reproduce:

  2. Attach it to a tunnel bore after some chest carts
  3. Put an ender pear in world anchor.
  4. Wait 12 hours.
  5. Server crashes, reproduces on restart.

Deleting named anchor cart (and only it) via MCEdit solved the problem.
Also, I will take a liberty to attach a tiny part of chash log because I truly believe it is the actual source of the problem (see EntityCartAnchor "requestFuel" method and ItemMap usage).

Fixed

So the only way to solve this issue is to delete the cart via mcedit?

I suppose you can install 9.1.x or even 9.2.x which has been already released. http://www.railcraft.info/releases
