Having a problem with kernel panics forcing a reboot of my main web server. Copy of the paniic along with reboot is below. Machine has run flawlessly for months now, with no changes of any kind recently. One item of note, it has a 4gig drive nfs mounted from a sun solaris 2.6 box which is our main file server. This sun box had repetive power failures due to a faulty ups 2 days ago (friday). While the drive comes up clean on fsck, I do recall notes to this being a potential problem in the archives. This problem did not occur until 2pm monday, crashing 3 times between 2 and 4 with the same error. Any pointers on how to fix this would be appreciated. Please cc me in any reply as I am not on this list currently.
