I have 2.2.5R running on a 486/33.  Sometimes (about 1 in 5) when I run
"systat -vmstat" I get the following:

Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0x229150f3
fault code              = supervisor read, page not present
instruction pointer     = 0x8:0xf011b45e
stack pointer           = 0x10:0xefbfff10
frame pointer           = 0x10:0xefbfff54
code segment            = base 0x0, limit 0xfffff, type 0x1b
                        = DPL 0, pres 1, def32 1, gran 1
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 197 (systat)
interrupt mask          =
panic: page fault

syncing disks...
<and so on>

Has anyone else had this happen?  Any ideas?  Thanks.

Kevin
