https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D185427 --- Comment #9 from eugen@grosbein.net --- (In reply to napTu from comment #8) There seem to be some problems with multithreading and/or locks within 9.x kernel/ng_nat code. 82576 just adds extra parallelism as it supports MSI-X = and multiple receive interrupts and increase probability of races within NETGRA= PH code. 82571 supports only single-threaded receive path. Why do you use ng_nat if you do not run mpd? Try to switch from ng_nat to ipfw nat and eliminate netgraph to simplify co= de path. Your 8.x crash link is broken (404). --=20 You are receiving this mail because: You are the assignee for the bug.=
