This just happened to me using Atik 383L+ and 2.5.14.
I am still having equipment issues and can't image - so I set up a sequence to take a dark library with biases. This ran for over 12 hours taking alternately biases and darks. But toward the end it had taken all the darks but it had a long sequence of just biases to take, and with zero delay. Once it reached that point where it was just taking biases quickly, with no darks to slow things down, SGP crashed.
I will see how it goes with taking flats later, but I would much rather not have to insert a delay when I don't need it. It sounds like it isn't guaranteed to help, either.
