SGP Crashes Taking Flats

A brief update. I had another error trying to run some flats with my Atik 383L even with a 15 second delay. I went to a 20 second delay and have just been able to get 100 flats run off without issue.

Now, here's the thing, a new Moravian G2-8300 arrived yesterday. More in hope than expectation, I ran a series of bias and dark frames with only a 2 second delay. It ran absolutely fine - 200 bias frames (0.1 sec exposure) and a variety of darks (75 dark frames in all).

One difference between the cameras is their cooling ability. The Moravaian says it can cool to 50 below ambient. The Atik claims 40, but in practice it seems only to get to around -37 to -38. I have been shooing the flats in June when the temperature inside the observatory is ~16-18 degrees. The Atik camera just about gets down to -20, but it will warm up somewhat once it gets into capturing and downloading frames. Could the issue be temperature related I wonder?
