I have been gathering as much information as I can on this matter, and it seems that so far, all cases have one thing in common.... The torrent client being used.
uTorrent 3.6.0
BitTorrent 7.11
qBitTorrent 4.6.2 or above
For some reason, these versions of these torrent clients seem to be having an issue. I wouldn't be surprised if this also affects newer versions of Libtorrent, as it is essentially the same base app as qBitTorrent.
Try rolling your torrent client back to a previous version and see if this resolves the issue.
FWIW: rTorrent seems to be another Libtorrent based software, so that may explain a few things. What version of rTorrent are you running?
