FreeBSD 5.2.1 kernel w/ SMP under high load = panic

I am running a Dual Xeon 2.8ghz w/ SMP, SCHED_ULE on FreeBSD
Whenever I load the server a bit more (let seti at home run, compile stuff in
multiple jails, etc), it will simple go offline. I confirmed with the
datacenter and it is indeed a panic, but the datacenter didn't give me the
panic message. I know for *sure* it's because of the high loads.
I need to sort this out, this is a powerful server being cut because of
FreeBSD/SMP, and I know there is a kernel option to prevent the panic, I
read about it ages ago on a forum. But I can't locate it. That user said
if he disabled SMP, panics would stop. But another user suggested adding a
kernel option (which I simply don't remember), and panics stopped, even
I tried KVA_PAGES=512, but it only caused another panic, this time as soon
as the system started up..
syncing disks, buffers remaining... panic: pmap_invalidate_range:
cpuid = 0;
boot() called on cpu#0
That was the most I got from the datacenter since the sysadmin is on
vacations and the guy I spoke to isn't very technical.
So, KVA_PAGES isn't the solution..
Here are my rc.conf & sysctl.conf & loader.conf:
These are my custom kernel options:
Any help is really appreciated, I have this server idling (compile lots of
stuff=die) for 2 weeks now :/
