Is there anythign I'm overlooking that would be causing the machine
to lockup
like this?
Your settings are tuned so high that you may be running out of KVA
memory. I bet the system would be happier if you let maxusers
autotune itself (and then maybe adjust it by a factor of 2 from
there), and if you reduced kern.maxfilesperproc to 2048 or less, and
reduced the TCP sendspace to 65K.
[ As a last resort, you might even try nixing the fastforwarding
option. It's well-suited for your task, and you do want it on if it
is working right, but maybe try running without it for a test. ]
