red hat answer......
Currently, there is no possible way to limit rss on a RHEL4/5 system. This is a known issue upstream. The best option would be limit as.
There isn't a good way to implement this, as it opens up for the possiblity of DoS attacks if you set the RSS low enough. Anything that uses glibc will have a good chunk of RSS dedicated to glibc, which is going to hurt them. There is also the question of what to do in NUMA situations.
