Insync runs for a while but the queue gradually fills up with stalled uploads. They never timeout so the number of active threads gradually reduced over a period of about 30 minutes, after which there are 12 stalled upload threads so no more uploads can start.
I can make it work again for a while by quitting and restarting the app but then is rescans the whole disk again and it is taking forever to upload all my files because I’ve had to restart it about 20 times already.
Not sure why the uploads are stalling but in any case there should be a timeout setting so the stalled uploads abort and/or retry after a few seconds of inactivity.
There should also be a setting to increase the number of threads because when 12 slots are full of stalled tasks then the whole sync process becomes frozen.
Note also that the scanning task at the top stops scanning new folders once all 12 slots are blocked with frozen uploads.
I’m running insync on Windows 11 with about 500gb of files to sync up to google drive, including many thousands of small files. It’s often very small files which stall, not usually large ones.

It looks like that bug was never fixed but that report was on linux.
