Dated 18th August from older issue
I've recently done some SP semi-survival testing and found that some machine buffers empty faster than they can be refilled with the RF power option enabled and using EnderIO's ender energy conduits(20,480 RF/t per connection) when the conduit line is connected to a multiblock capacitor bank with an input/output of 375kRF/t per multiblock capacitor bank face.

The particular machines are:

industrial grinder
industrial electrolyzer
It's occurring for recipes that have a 30-100 EU/t usage within 3-5 sec and for the above machines with 10k EU internal buffers. Should they be draining that fast??

Now for the newest things
Upon updating and launching the pack after a few weeks of not touching it; ive found an interesting one

Edit:
As per the 18th August comment its not occurring for those 2 machines but the Industrial Grinder Instead. 1 Bauxite ore drains it's internal buffer down to 4.6k EU/10k EU with the energy not being replineshed by the ender energy conduit connection

To clarify the invisible mulitblocks got 3 more pics;

There behaving like the "Unstable ingot block" from Extra Utilities 1(1.7.10) which was purposely designed for X-Ray function.

Closing this as it contains more than one issue. and I think most of them are fixed.
