Openvpn tap uses 99% cpu time

[Emile Coetzee]

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
used

ktrace -d -f openvpn.dump ./tapserver.sh

This captured all the information for the parent PID 1082

 

I then watched top in a second session and identified the PID (1083) of the
openvpn process that was using up the CPU time.

 

I then ran 

ktrace -p 1083 -f openvpn2.dump 

 

This produced no data at all.

 

The dump is fairly large so I have dropped it here:

If required/allowed I can post it to the list.

 

Regards

Emile
