adding torrent can hang at 0% "checking files"

[milahu]

im adding torrents with existing files

in rare cases, maybe 5%, the torrent is added but then its stuck at 0% "checking files" or its stuck at 100% "checking files"

workaround: remove and re-add the torrent this can be necessary multiple times

i have configured rqbit to use only 2 blocking threads to reduce memory usage

i have about 250 torrents with total upload speeds around 12 MB/s

so maybe the 2 blocking threads are always busy seeding
