You cant solve the UDP problems that gerph mentions, but you can almost completely alieviate the exhaustions by substantiall increasing the large and small mbuff allocations.
As we are no longer running 1MB machines we dont need to restrict the pool to 200K, and can easily give it a megabyte or more.
When using Access as long as each transfer burst is quite short, it will continue without problems. With the default mbuf poll you have to reduce the wimpslot of a filer copy down to its monimum of 52K. If you quadruple the pool, the filer action slot can be around a megabyte quite happily.
I posted instructions on how to increase the mbuf pool to the Select mailing list and newsgroups a while ago. A smartgroups or google search should turn them up.
