Hi Clemens,

By not solving any de novo structures...

It does go to sleep, but is not shut down.

The check_server script tells me that there is a server running.

It does use a DHCP server, but it gets a fixed IP address from that server.

Yes, I also get it when logged onto the computer itself and using localhost. Looking in the SUSHI file the most relevant-looking lines I can find are:

The last 4 lines are then repeated at least 10 times.
Does this give you any further ideas?
