"But I'm already using TCP!" I was about to say - actually turns out I'm
not, and I have to wonder if my bright idea to change to UDP (probably for
performance reasons, though I don't think it made any difference)
coincides with the problems I was seeing. I'll give it a try and see how
I get on. I think I'll still follow Daniel's kind suggestion for a
replacement interface card, but this may well make things a bit less
painful in the meantime.
I'll resume my network-intensive KDE build tomorrow and post my findings
(or, hopefully, lack thereof as far as outages are concerned!)
