Page fault while in kernel mode (FreeBSD 4.6.2)

Tue Apr 8 13:18:49 PDT 2003

Hello,

 Recently a server of mine has been rembooting quite often... I thought it may have been related to a UDMA 33 and UDMA 133 drive on the same chain, so I replaced them.  But it continues to persist, especially when doing disk intensive work. 

 For instance, just today, I see this...

Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0x56

instruction pointer     = 0x8:0xc020ecd4
