Hmmmm. I don't know, maybe you really do have a machine too loaded
for the KVA you have configured...
I have to re-iterate that it's extremely important that you
double-check that you are in fact in sync with the latest -current and
_NOT_ RELENG_5_1. Make sure you're building at least version 1.73 of
src/sys/vm/uma_core.c (grep FBSDID src/sys/vm/uma_core.c).
With that said, you can try the following:
options KVA_PAGES=400
in your kernel configuration file.
Following that, you can do this:
kern.vm.kmem.size=400000000
In your /boot/loader.conf
Make sure to not set NMBCLUSTERS too high. Around 8K is probably more
than enough, but you should look at how much you're using on average
with `netstat -m' and then set the number to roughly 3 times that.
If following this your crash persists, even if after a longer time,
then I would suspect (another?) race. Again, I have to re-iterate
that you really need to make sure you're supping to HEAD:
*default release=cvs tag=.
