Hi
One of my DL360G5 boxes running 7.0 had a panic this night:
jb-2 ~$ uname -rsv

The config is a GENERIC with some pf, IPSEC and ALTQ stuff enabled.

Previous frame inner to this frame (corrupt stack?)
(kgdb)
Please let me know if I can help with anything else. Is there any way
to know which app caused this?
I Did some googling with only one or two similar crashes as result,
although the hits didn't give much..
I've never had this crash before.
Thanks
