Hi
One of my DL360G5 boxes running 7.0 had a panic this night:

jb-2 ~$ uname -rsv
FreeBSD 7.0-RELEASE-p4 FreeBSD 7.0-RELEASE-p4 #2: Thu Sep  4 10:49:27  
CEST 2008     johan at jb-2:/usr/obj/usr/src/sys/DL360G5

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

jb-2 /usr/obj/usr/src/sys/DL360G5# kgdb kernel.debug /var/crash/vmcore.0

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
