The vnode subsystem is *VERY* sensitive to running out of KVM, me
I'll try this if I can tickle the bug again.
I may have just run out of freevnodes - I only have about 1-2000 free
right now. I was just surprised because I have never seen a reference
to tuning this sysctl.

I'm a little confused. What state is the vnlru kernel thread in? It
sounds like vnlru must be stuck.
Note that you can gdb the live kernel and get a stack backtrace of any
stuck process.
gdb -k /kernel.debug /dev/mem (or whatever)
proc N
Ack, only 512Meg of memory? :( k, now you are beyond me on this one ...
I'm running 4Gig on our server, with 2Gig allocated to kernel memory ...
only thing I can suggest is try slowly incrementing up your maxvnodes and
see if that helps, but, I'm not sure where your upper threshhold is with
512M

Ack, my fault ... sorry, wasn't thinking :( RELENG_4 is correct ... I
