ktrace help

[Anton Shterenlikht]

I suspect that nginx causes my box to reboot.
I don't get a panic or anything in the logs,
just a reboot. So I wanted to see what nginx
is doing prior to reboot with ktrace.

I launch ktrace as "ktrace nginx",
and I see that ktrace.out has some data.
However, after reboot, it's empty:

-rw-------   1 root  wheel    0 Nov  6 09:04 ktrace.out

Is this expected?

Thanks

Anton
