What is your NMBCLUSTERS set to? And in cases of "high traffic," what does `netstat -m' show for number of clusters and mbufs "in use?" How much of mb_map (%) is in use? If any of these are relatively close to exhaustion, try increasing NMBCLUSTERS in your kernel configuration and rebuilding. > At home I am using this Laptop in a 100MB-Network and am able to almost > saturate the link without any problems.
