Problem Direwolf 1.0.23 Server Crash

[ThermalCraft]

Hi,

We run a Direwolf20 1.0.23 server, everything has been working fine for last week since we opened. At first I thought iConomey was causing crash as it kept spamming logs saying its running slow. and I switched to FE-Eco, however we are still getting server crash but the slowness has disappeared.

We get the crashes around 4 times a day or more.

Server Version:
Cauldron-MCPC-Plus version git-Cauldron-MCPC-Plus1.6.4-1.965.21.89 (MC: 1.6.4) (Implementing API version 1.6.4-R2.1-SNAPSHOT)

ServerStart.sh:

It seems to be complaining about the IC2 energy net. Try using Opis to zero in on the cause of the lag, or at the very least make sure everybody's IC2 setups are kosher(No wires going everywhere they don't need to be, no huge banks of solar panels/watermills/windmills, no machines with ridiculous numbers of overclockers).
