Hi,
I run openvpn with --verb 9 and got a lot ouf output, which I dont understand 
- only see between all the masses of messages the on which always appears on 
the console when unplugging the pcmcia card:

write UDPv4 []: No buffer space available (code=105)

A little piece of the output with --verb 9 is:
