FWIW, I could not reproduce any such problem here.  I ran three test
cycles with numberOfRows=300000 and ndatabases=3 under PG 7.4.3 and
another three under CVS tip (amounting to something over six hours
total runtime).  I saw no errors whatsoever.  I was using Red Hat 8.0
with 2.4.18-24.8.0 kernel on a Dell P4 desktop machine.

I'm leaning to the theory that you've got intermittent hardware
problems.
