rtorrent downloads broken, possibly related to recent mmap work
Running DragonFly v18.104.22.168.gdc43b7-DEVELOPMENT, x86-64
Since upgrading to recent master, rtorrent downloads have been frequently failing with the message "hash check on download completion found bad chunks". I've never that message from rtorrent before. I tried setting machdep.pmap_mmu_optimize=0 and the failures stopped.
Possibly related to this rtorrent bug report:
Thanks for adding that link, Francois. If this is in fact a bug in rtorrent, I don't have much hope that it will be fixed, given that this bug report is 6 years old.
