This might be because the owner is restarting the server, or one of the following items is bugging up the server: Redstone Timer World Anchor Collectors/relays Any of these can crash servers, or it may be that someone has crashed the server using computer craft, hope this helps you

This is because you don't have enough energy in your MFSU, Rotary macerators take a lot of power, that or it may be too high/too low a voltage, but try the following things: 1) make a more powerful energy source or many more power sources to give you energy 2) try using transformers (start with HV, then MV then LV) and test it between some until it works 3) use glass fiber cables from the MFSU, you only use HV cables when using nuclear reactors, also may be the reason you're taking damage when you go near it try these and I'm sure it will work fine afterwards
