>Environment:

System: FreeBSD process2.ireit.pro 7.0-RELEASE FreeBSD 7.0-RELEASE #0:
Tue May 6 14:34:50 CDT 2008
root@process2.internetreit.local:/usr/obj/usr/src/sys/GENERIC amd64
<mailto:root@process2.internetreit.local:/usr/obj/usr/src/sys/GENERIC%20
amd64> . ULE scheduler enabled, but crash happens regardless of this
setting.

 

8 core (4 dual core) opteron 2.2GHZ CPU's 32GB (16x2) RAM installed

 

>Description:
Every 20 to 30 days, the server will kernel panic. No core
dump is written, and this message appears on the console:

 

Uptime: 20d13h46m33s

Fatal trap 12: page fault while in kernel mode 
cpuid = 7; apic id = 07 
fault virtual address = 0x28 
fault code = supervisor read data, page not present 
instruction pointer = 0x8:0xffffffff804aac80 
stack pointer = 0x10:0xffffffffae388b30 
frame pointer = 0x10:0xffffff00010f3000 
code segment = base 0x0, limit 0xfffff, type 0x1b 
              = DPL 0, pres 1, long 1, def32 0, gran 1 
processor eflags = resume, IOPL = 0 
current process = 36 (irq18: ciss0)

 

The servers will resume normal operation after a reboot (usually
requiring an FSCK)

      

>How-To-Repeat:

We cannot force this to happen. It occurs every 20 to 30 days.

      

>Fix:
