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=.
