>Still no diagnostic info I'm afraid. What is needed is for the problem to be reproduced, with the openvpn process which is spinning under 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. Check that you have kdump output from the openvpn process itself. Use the -T switch of kdump to get absolute timestamps, watch the wallclock time on your system when the spin happens, and post an excerpt of the kdump output at that time, which should tell us where openvpn is spinning.< Okay I finally have a ktrace of the offending process. You can view it here: http://www.clarotech.co.za/dump/openvpn2.txt Regards Emile
