Hi,
this is unusual, we have multiple installation on linux that are not
exhibiting this problem (but I don't
think we have production instances on Ubuntu).

Wondering if you have it setup with extra security, disallowing opening TCP
ports at all?
Normally ports above 1000 are fair game.
The error trought google translate is:

"Error opening port H2 TCP Server (tcp: // localhost: 46303) (. Port is
possibly already in use), reason: Timeout"

Hum... possibly already in use... that is also strange thought, H2 server
should be trying to open a random
port.

I'm cc'ing Daniele above, Daniele, I was wondering, any way to make H2 not
start in server mode?
I guess that's useful for debugging, not sure if needed for actual
production (let us know if it is).

Cheers
Andrea
