Anyone else running into this?

is this 2.2.0?
what version of windows?

[janjust]

check the MTU size of the tap-win32 adapter vs the value specified with '--tun-mtu' .

It was 2.2.0 and Windows 7. I downgraded to 2.1 release to test, and it worked fine.

FWIW:
I was just able to reproduce this error by misconfigured a server and a client: the server did 'comp-lzo', the client did not. In this case I also see 'error=122' messages.
