Panic=page fault

[static]

Pfsense 2.0 Beta3 stops responding every day with the following message:

The output is alot for me to write everything but this is some of it:

fault virtual address = 0xc
fault code = supervisor read, page not present
code segment = base 0x0, limit 0xfffff, type 0x1b
current process = 12 (irq17: rl0)
trap number = 12
panic = page fault
cannot dump.  Device not defined or unavailable
sleeping thread (tid 64046 pid 12 owns a non sleepable lock
panic: sleeping thread

I've tried changing Harddisks, and reinstalling to the current snapshot June24th 2010 but I'm still getting the same problem.
it seems to occur sometime in the afternoons.

I've 4nics, 2WANs and 2LANs, with Load-Balancing on the WANs and a captive portal enabled on both LANs
I'm using the traffic shapper as well as traffic limits via the captive portal
I've about 150pass through IPs and 200 pass through mac addresses.

Please advise on what could be the cause of this problem

Is the error always on "rl0"? (See the current process)

You might have a flaky network card, or some other faulty hardware.
