Nopers. No nfs... nothing at all fancy with the drives except the raid.

To ammend this slightly.. When running the PAE kernel, they will

I have 3 dell machines with 2x xeon procs, 8G of ram, and a half
terabyte raid 5. I attempted to run the AMD64 distribution on
these boxes which was fine for everything except mysql, (which is
all these boxes are going to do) so I reinstalled 5.4 i386.
uname -a looks like (hostname obscured):
FreeBSD myhost.mydomain.com 5.4-RELEASE-p9 FreeBSD 5.4-RELEASE-p9
#2: Mon Jan 16 23:27:12 PST 2006 [EMAIL PROTECTED]:/usr/
obj/usr/src/sys/SMP-PAE i386
My problem is, if i don't enable PAE in the kernel, i can only
address half the ram in the boxes, but... the machines are stable.
If i do enable PAE, i can address all the memory, but they randomly
reboot without dumping any errors or logging.
To enable PAE, i am building and booting off the following kernel
config:
<snip>
include PAE
ident SMP-PAE
options SMP
options KVA_PAGES=512
</snip>
I added the KVA_PAGES options hoping to stabilize the machine
(doesn't seem to have made any difference.) The only other tuning
i am doing at the moment is in loader.conf:
<snip>
kern.maxdsiz="2147483648" # Set the max data size
</snip>
When i boot without PAE I use the generic SMP kernel, and the
machine is stable.
I know that there are a number of other kernel tunables i could be
tweaking, but I am not really sure where to start as the machine
dies silently. I was hoping that someone who has run a stable PAE
kernel with 8G of ram + could point me in the right direction.
Thanks,
