You'd probably get more answers if you had selected a subject line
like "Problems with multiple Ethernet boards"

I don't think they're a significant factor.  I suppose that 8 MB of
RAM is not exactly too much, but I don't think that that's the
problem.  I've run routers (one Ethernet board, one ISDN board) in 4
MB, and didn't have any memory pressure.  I don't expect the
additional boards to make any difference.  I'd guess that you might
have a driver problem.  Which boards are you using?
