Resolving Excessive Swapping in RHEL 4

RHEL4 tends to swap very heavily on some systems, even when there is plenty of free memory. This is due to the default setting of vw.swappiness (sysctl setting) being excessively high for most systems (60 is the default). If you encounter issues with this, try editing /etc/sysctl.conf to include:

vm.swappiness = 10

and run
sysctl -w vm.swappiness=10

This should be a better setting!
