I think this happens because OpenVPN tries to write Ethernet frames to the tun 
device. See the warning in the log:

'dev-type' is used inconsistently, local='dev-type tun', remote='dev-type tap'

Tap is not supported see the FAQ for more details.

The new log still states: 'dev-type' is used inconsistently, local='dev-type 
tun', remote='dev-type tap'

You can the tap only on the server side (or your adminstrator)
