Hi all,

Here's the situation:

- Base in a fully chunk-loaded area (ChickenChunks loader, circular 3-chunk radius, encloses entire base and whole ME network.)

- Medium sized ME network, one 6x6x6 MAC, single controller, about 30 interfaces and 40 import/export busses.

- ExtraCells used for fluid storage, one 16K cell for a few misc. low-volume liquids and everything else (lava, fuel, etc) on fluid storage buses with steel RailCraft tanks.

- Fluid import by tesseract to liquid interfaces. Solid objects imported from quarries by tesseract to regular ME interfaces.

- I am the server owner, and have operator privs. ChickenChunks config is set to allow 5,000 loaded chunks per player. I probably have about a hundred chunks loaded, across several dimensions. Definitely nowhere even approaching the 5,000 chunk limit.

Behavior:

Everything was great, working well until this morning. I logged in, all systems were running properly. However, when I took a Mystcraft portal to the Nether and then returned to my base the ME network was completely dark. Controller offline with no energy.

I break the controller, and replace it. Everything springs back to life, it fills with energy, all is good. But now this keeps happening. Every time I leave my base and come back, I return to find the ME system is shut down.

Power is being supplied by high voltage solar panels, to a bank of MFSUs. These are connected by glass fiber to an ME power relay, which is hooked onto the ME network via ME Covered Cables. Breaking and replacing the Power Relay does not cause the system to come back. The MFSUs are filling much faster than the power is being drained - they never get below about 95% full at any time.

If I remove the power relay and run the system off RF instead (150,000,000 RF EnderIO capacitor bank via a short run of Redstone Energy Conduits to the back of the controller), the behavior is a little different, and even more strange...

Leaving the area and returning to an RF powered controller does not result in a total shutdown. The controller still has power. However, every other part of the ME network is dark and says it cannot communicate with the controller. Once again, breaking the controller and replacing it makes everything spring back to life properly, until I leave the area again.

The system has been running essentially unchanged for about a week now, with none of these problems. I'm not sure what changed to cause these problems. I don't remember changing anything major on the ME network recently - mostly been working on bees in a different area.

Any ideas? I'm running dry here.
