If you haven't checked out Netcordia's list of Tech Tips you might find it useful. One of the latest is a Tech Tip on Cisco buffer tuning. The tip explains that that some buffer tuning will improve Cisco routers' "excellent job at handling network traffic." According to the tip: "In some rare cases, an IOS bug will never release buffers, eventually consuming all of memory. Watching buffer creation and the total number of buffers (or memory) in use will alert you to places in the network where buffer tuning may be helpful."
