Ar you scanning over the network. It would be worth testing the USB
interface first. And if you can get Rolf the logfiles of a Windows scan
and the Linux scan I am sure that he will be abler to get this sorted
out. This is definitely worth spending some effort for.

The logfile you show here may be pointing to a bug in the network code.
In other cases I have seen a faiure to open a tcp connection, this was a
bug in the network code. Did you test with the latest code from git?
Could you please try the same procedure over USB (disconnect the network
connection for the time being)
