I have a similar setup, but we now _always_ use local drives for swapping,
not Network drives - this is after we had several problems with certain
programs and paging causing hangups, also local swap is usually faster.

However, this is not the same problem, I just tried out
-> pagetest 30000
on two machines, one failed at page 6140 in the manner described above, one
completed fine. Both machines are 486's (one DX2-50, one DX2-66) with 8Meg
ram. Both are running QEMM (standard setup for this network) - so that's not
the problem. DJGPP is all run from the network drives, so both machines had
same setup for that.

I suspect some wierd config problem - maybe hardware specific as the two
machines I've so far tried are different manufacturers. I might run more
tests on a range of machines - I'll let you know any interesting results.
