Regular kernel panics on 4.7-RELEASE system

Apologies if I've forgotten anything, this is the first time I've had a  
problem like this...

I have a 4.7-RELEASE box that is suffering regular kernel panics.   
Unfortunately, they happen at about 3:15 AM every day, so I've yet to  
actually witness one in person :).  I have, however, followed the  
directions at  
http://www.onlamp.com/pub/a/bsd/2002/04/04/Big_Scary_Daemons.html to  
hopefully provide someone here with enough useful information to  
address the problem.

The machine is a Dell 2650 running primarily as a file/print server to  
a number of computer labs of about 400 machines (although it also  
functions as a rembo image server and squid proxy).  It mainly stores  
applications, which are run off a samba share and user home directories  
(again, accessed via samba).  It has a largish filesystem (~200G) on a  
Powervault 220 attached via a PERC3/DC controller (amr) that most of  
the data is stored on.  The OS is on a pair of internal 18G drives  
attached to the internal PERC3/Di controller (aac).  It is attached to  
the network with a Netgear GA620 fibre NIC (ti).

I'm guessing the panic is being caused by "something" fired off by the  
/etc/periodic/daily scripts, since they start running at 0300, although  
running each one manually does not cause a panic (or hasn't the times  
I've tried it).  It appears to be something specific to this system, as  
we have quite a few 2650s here running various things from squid  
proxies to development servers and none of them have exhibited similar  
problems.

All the data on this system was recently migrated off a  
recently-decommissioned Dell 6300, which was also exhibiting identical  
mysterious early-morning reboots.  At the time, due to workload I  
didn't bother chasing it up (since it was effectively not impacting on  
services) and was half-hoping the new machine would fix it.  At least  
the continuing problems minimises the chance it's hardware-related :).

Here is the relevant system info.  If I've forgotten anything, or there  
is anything more anyone needs to help fix the problem, please let me  
know.
