I was referring to this in the blog:
So be aware that using this method will require considerably more memory than rendering on a single instance. Apple recommends 1 GB RAM per instance but again, this depends on the media you are transcoding to
The current manual recommends 2 GB per instance.
Sorry to hear old problems have returned – along with the new ones.
If I were in your shoes I would also be pretty ticked off…but almost surely it's more complicated than Compressor-QMaster alone.
According to your profile you are currenly running ML on a computer you purchased in 2011. What did you upgrade from and did you do a clean install? Did these problems surface first after the upgrade to 10.8?

Okay, here's an update...
I still could not get a batch to avoid fail, even after trying EVERYTHING on this post:
However, on a whim, I tried one little (seemingly) insignificant thing in Compressor, and suddenly everything works. The "Elementary Stream" setting I was using to encode a blu-ray asset had the frame rate set to "Automatic." When I imported the source file, that pop-down menu for frame rate changed to "24." That is the editing timebase I used in Final Cut Pro 7. When I changed that to "23.98," voila! No issues with encoding (though I have yet to attempt an encode using a cluster... this one was completed using just "This Computer").
After everything I've read in the last week while attempting to solve my issues, I've been told that 24 is actually 23.98, yet Compressor has them as two different settings. If I was editing in 24, I'm not sure why 24 would cause a crash in Compressor, but at least I've figured this out. I can't understand why a Compressor setting would inaccurately recognize the frame rate of a source video like this, but oh well. At least I know now.

24 and 23.98 are not the same although they are often confused. 24fps is the rate that film is usually shot at. When it's transferred to video, it's usually slowed down slightly to about 23.98 so that 3:2 pulldown can be added to make a 29.97 frame per second video (NTSC - North American standard). In Europe, the film is usually just sped up to 25fps the PAL - European video standard.
And computers can play any of these frame rates.
To make things more confusing, complicated and frustrating, I'm now preparing a documentary that was shot and edited at 29.97 fps for conversion to a digital cinema print which has to be 24 fps (not 23.98). Oy.
