Yeah, windows xp (I think we have one with no SP, and the rest with SP1). We
have some win2000 sp4s but they don't run the offending app (rather other
ones that don't show the problem).

But the network bandwidth isn't

I looked and it didn't seem particularly related, seeing as they are XP
boxen.
CPU usage for the postgres machine is also very high, getting regularly up
to 50% for a single connection. I will try a vacuum full but I am pretty
sure that won't make much difference. Maybe it is related to network

I will have a look with ethereal and see what I can gather.
