--- Comment #5 from Mark Johnston <[email protected]> --- (In reply to Michael Meiszl from comment #4) The sysctl disables an optimization such that sendfile no longer uses "unmapped mbufs". This avoids a problem triggered by ipfw which results in a crash. The sysctl can be added to /etc/sysctl.conf of course. I think we should make m_pullup() handle unmapped mbufs, since that's the heart of the problem, but I haven't looked closely. I hope Gleb can comment further. -- You are receiving this mail because: You are the assignee for the bug.
