Had a sequence going last night and while shooting my bias frames 38/50 files were being saved with 0 bytes of data. I tried a few manual captures and it produced the error of "Image save error: error writing to fits file." This has never happened before and all lights, darks, flats and even 12 bias frames worked fine. What is really confusing to me is how mid-sequence image saving would corrupt and persist beyond EKOS/KSTARS restarts and even Astoberry restarts and update checks. Not sure how to produce a log file for anyone but willing to try if you can provide the steps. Would love to have a deeper understanding of the error. No code is provided and nothing in the bottom status window. Thanks in advance to anyone to can help.
