Maybe this is the same issue as Fits-viewer crashing Kstars. When taking previews, it works, but when stting a sequence, download takes forever and eventually fails - no fits-viewer loads (or loads and disapperas in a blink).
I have a Canon 1000D, Indiserver running on a Stellarmate R-Pi. Log attached (I hope).

So it looks like you're using an external drive? maybe that drive has some issues? Please double check.
OK, after reformatting my external drive, it seems to work. But.... then i freezes when trying to focus. I have a DIY arduino box with moonlight driver. I just freesez after first exposure. Any ideas? Log file attached.
Can you enable "Focus" logging as well? I just added a capture timeout checked for Focus module as well in case for whatever reason the driver hangs on capture.
