Hmm... Much though I love APM for the charging benches and (now that I know about them) the storage monitors, I'm having a couple of strange problems. I'm not exactly sure what is at fault on both of these cases, as they seem to only happen while I'm logged off. First, the relevant (I think) version info:
Forge 6.4.1.430
IndustrialCraft2 1.110.137-lf
APM 1.1.42 for IC2_1.109
GregTech 2.54b
So, here are the two strange issues that are taking place...
First, I have repeatedly logged in to find my HV Charging Bench and the energy storage device that feeds it drained. No items are left in it to charge, it's not being provided a redstone signal, no other devices on the energy network are drawing constant power. I'll leave with full power in the HV bench and come back to find my whole network dry. Since removing the HV Charging Bench from my network there have been no problems.
Second, I have two GregTech energy storage systems that I am trying to use with Storage Monitors. The first is an LESU with enough blocks added on to provide 28m EU storage. The other is an AESU. I've created the cards, linked them with the devices, placed them in the Storage Monitors and everything works absolutely perfectly... but when I log back in after some amount of time with nobody on the server, both the cards have vanished.
In either case, it -seems- that these two issues happen at some point after a daily reset that the server provider schedules, but when I do a -manual- reset, everything seems to be just fine. Also, in the case of the charging bench problem, another set-up which has ONLY a charging bench, MFSU and a reactor seems to hold its charge (though it exists in a separate (mystcraft) world AND I haven't heard of any of my other players having the same kind of problem.
As to the second case, I'm not sure if that might be a GregTech problem or an APM problem, but as I said - everything does work just fine. It's simply that the cards vanish without any explanation that I've found.
