My server keeps crashing (Mindcrack v6)

[Spikerbond]

I have been getting a lot of the "[IC2] API ERROR: ic2.core.block.machine.tileentity.TileEntityRecycler@115edd85 didn't implement demandsEnergy() properly, no energy from injectEnergy accepted although demandsEnergy() returned true." errors recently, and I know that it is a documented bug and they are working on it. But it appears that my server crashing has a different cause. Any ideas on how to fix it?

(It wouldnt let me post the full crash report so I just attached the file below)

It's a know issue with the current ic2 build in the modpacks, we have to wait for ic2 to bring a stable update and then wait till it get's implemented in the modpacks
