Thanks for this. If this is the correct trace, of the correct process,
then it looks like OpenVPN is hanging immediately on opening the tap device.

ktrace. You might need to hack your script to do this i.e. run openvpn
directly from ktrace. Let it run for a bit, let it spin, then kill it.

running a kdump on it produces no output.

Shouldn't. :-) You need to run ktrace then kdump to dump the trace.
Correlate the cpu spin with the wallclock time in the kdump output, and
paste an excerpt of what you get -- it sounds like
Hi Bruce
I have run a ktrace as you suggested
I put the following in a script /usr/local/sbin/openvpn --daemon --config
/usr/local/etc/openvpn/tapserver.conf and called it tapserver.sh and then
