Network Instability when upgrading to 4GB of RAM

[Paul]

I had some similar issues for some reason.. Check the output of netstat -m
and see if the mbuf clusters in use line if the total is anywhere near 
the max.   Mine was maxing out and causing some very weird problems with 
no errors in any log anywhere.
