The network connection goes down. So I guess it's the cards -- all three of them.

Smaller transfers are fine; it doesn't blink at several hundred, surely.

It seems to vary with the number. I've tried different sets of files and I get the hang
after some number. Don't know if it's the same number -- but it definitely isn't the same
file.

Yes, it does. Where? Not in the cards (since it happens with several) or in the drivers (for
the same reason) -- so I'm tempted to suspect something somewhere else in the system, such as
an onboard cache or some buffer memory that gradually gets filled up. But those are the purest
speculation.

I don't remember having any such issues with this computer the last time it was in general
service, which is now a few years ago. (In the meantime it's been doing simple print/samba
server duty at home.) Maybe I should just retire the old hardware. But perhaps there is 
something that can be done...
