Yahoo noticed a deadlock in the vnode recycling code. If your machine
below is hitting the kern.maxvnodes limit it could be the same thing.
The way to tell is to generate a kernel core along with the debug

and backtrace each locked-up process to see if any of them are going
through the recycle code.
Yahoo has a fix for that particular problem that they and I are testing.
