Crash during fits write

Last night, my session died during an imaging frame download. This is from a QSI camera and I got about 3MB of the usual size 17MB. The last line is:
SaveFileBmp16: Traversing and persisting bitmap data…

I see no other oddities in the PHD log. Attached is the log. Any help would be greatly appreciated.

Not a lot to go on unfortunately. Anything in your system logs or event viewer around that same time that might indicate a camera disconnect or other odd behavior?

Thanks,
Jared
