Fatal error (crash) when canceling
Posted: Fri Jun 19, 2020 10:14 pm
MakeMKV sometimes tends to become unresponsive and then crash when attempting to cancel a backup operation. I'm not sure exactly what causes it, i.e. why it happens some times and not others, but it does seem to happen more frequently when the operation is canceled right away, while still in the decryption phase. In fact, that's the only time, to my knowledge, that I've had it happen.
Usually, when cancelling, at least after decryption is done, it cancels immediately. Sometimes, however, it takes a while, seeming unresponsive. In these cases, it sometimes cancels properly, but usually it doesn't, and instead becomes completely unresponsive before crashing. I'm not sure, but clicking the cancel button again, due to the cancellation seeming to be stuck, might increase the risk of it crashing, though it isn't necessary to cause it.
I got this error in the log when it took a while to cancel but ended up successfully doing so:
and these when it crashed:
so it seems the 122 error may be a clue.
It also says "Using LibreDrive mode (v06 id=94DE7D3D0ADE)" though I'm guessing that's pretty standard stuff, but might be important for debugging.
Let me know if I can provide any more info. This is on Win10x64, version 1.15.1.
