The error indicates that too many receive buffer descriptors
were freed from the receive chain.  The driver must be losing
count somewhere.  The process for duplicating the error sounds
simple enough, how much data is in your NFS mounted directory?
Are you using TCP or UDP for the NFS mount?

Any idea what type of network activity is happening just after
/etc/rc.d/netif start (DHCP, NTP, anything else)?
