Frank,

No error visible.

A manual transfer was also very slow, a reboot of the machine solved
that.

Nothing changed for a good while, only I did reboot the network
equipment some time last week. I beleive the duplex did not get
negociated properly after reboot.

That's yucky :)

OK that was only a network problem it seems.
