Fresh 7.0 Install: Fatal Trap 12 panic when put under load

[Michael Grant]

My box crashed again:

panic: kmem_malloc(4096): kmem_map too small: 1073741824 total allocated
cpuid = 0
Uptime: 33d11h12m58s
Dumping 3327 MB (2 chunks)
  chunk 0: 1MB (151 pages) ... ok
  chunk 1: 3327MB (851568 pages)  <---hung here

Still no valid dump.

There is 4gig of physical memory in the machine.

In /boot/loader.conf, I currently have the following:

vm.kmem_size=1G
vm.kmem_size_max=1G
vm.kmem_size_scale=2

and in my kernel conf file I have:

options         KVA_PAGES=512

It stayed up for 33 days this time.  Is there anything else I can do?
