yes i did. The 2.4x Rh kernels actually aren't right in their swapping behavior. it really nailed my samba server here at the house and caused massive swapping and load issues on a friend's gaming server. i don't know what it is about RH's 2.4x kernels but they swap and won't give the cache memory back. I have more than 6 ipcop firewalls based on 2.4 kernels(not RH) and they won't swap unless you actually exhaust physical memory. The issue is the RH 2.4x kernels which for some reason continue to swap even with 500 MEGS of cache memory available to take back. 2.6x runs much better and actually obeys the swappiness commands. Even the various patches done by Rh on the 2.4x kernel never reduces this behavior.
