[DragonFlyBSD - Bug #2441] rtorrent downloads broken, possibly related to recent mmap work

[Francois Tigeot via Redmine <bugtracker-admin@xxxxxxxxxxxxxxxxxxxxx>]

Issue #2441 has been updated by Francois Tigeot.


We cannot completely exclude a DragonFly issue either.

It would be interesting to get both good and bad copies of the same file.
Knowing the corruption pattern may help find a possible root cause.

Bug #2441: rtorrent downloads broken, possibly related to recent mmap work
http://bugs.dragonflybsd.org/issues/2441

Target version: 


Running DragonFly v3.3.0.165.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.
