Subject:   Page Faults FreeBSD 2.5 and Procmail

I am having problems with two of my FreeBSD machines having Page Faults due
to I think Procmail. Both are FreeBSD 2.5, both have been running procmail
for about 2 years, neither has had any significant changes recently yet both
started page faulting last night beginning I believe around 11:00PM. I
tested the procmail theory by sending a small test mail message and teh
system crashed immediately yet a small test message to a user not using
procmail and it delivers fine. I read an article on kernel debugging on
FreeBSD (see below) and have prepared some of the key information. I
initially thought it might have been a physical hard drive or swap partition
thing, until the second machine had the same problem at a different site
using different equipment. I upgraded one machine to procmail-3.14 with the
same results. My guess is a kernel bug. Any Ideas or people having the same
problem? I know someone with FreeBSD 2.6 using procmail and is not having
the problem.

Some of my Page Fault details are:

Fatal Trap 12: Page Fault while in Kernel Mode
Fault Virt Address=0x0
fault code  = supervisor read, page not present
instruction pointer is 0x8:0xf01e83b

Output of "nm /kernel | grep f01e8"

f01e8b24 t _blink_screen
f01e80b8 T _copy_font
f01e8acc t _do_bell
f01e891c t _draw_cutmarking
f01e85b4 t _draw_mouse_image
f01e8a84 T _load_palette
f01e853c t _mouse_cut_end
f01e8498 t _mouse_cut_start
f01e8554 t _mouse_paste
f01e8a1c t _remove_cutmarking
f01e886c t _remove_mouse_image
f01e8a50 t _save_palette
f01e81b8 t _set_destructive_cursor
f01e82d8 t _set_mouse_pos
f01e8e70 t _wdattach
f01e8be8 T _wdc_pci
f01e8bf8 t _wdprobe
f01e8be0 F wd.o

Nothing looks obvious here. I was hoping to see an entry that might tell me
something, but instead I feel I am going in the wrong direction.

Thanks for any ideas,

Harry Patterson
