It came from wrong sx lock usage inside ipfilter. I tried to use recently imported (into -current) ipfilter 4.1.23 and found it is almost unusable (at least ipnat): it's very unstable (several hangs or deadlocks per day), it does leak memory. I've spent some time on fixing ipfilter's bugs, then sent report to ipfilter's author. Unfortunately, i failed to get any feedback. You can get patch here: http://people.freebsd.org/~oleg/patches/ipfilter.r70.diff I would not swear it's 100% correct, but it should make ipfilter much more stable. It does following: - sx locks converted to rwlocks. (this should be done, cause pfil(4) uses rwlocks, which are not sleepable). - fixed memory leak inside nat_getnext() - fixed several improper checks of array's boundary. - added some missing mutex_destroy() calls - ipfilter's attaching/detaching procedure changed a bit in order to fix some LORs. -- Oleg. ================================================================ === Oleg Bulyzhin -- OBUL-RIPN -- OBUL-RIPE -- oleg@rinet.ru === ================================================================ [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFGpGSkryLc73jOEF8RAqNqAJ9TSnEhRQOzipuk947mfxRY01xiuACfVOZ5 DLsLRoxvKu3v3qaKLolw9l8= =DMlh -----END PGP SIGNATURE-----
