Swap usage

[Robert Fitzpatrick]

I've read a lot of posts on this subject and realize swap usage will 
happen even if you have plenty of physical memory. But are my usage 
results normal? ....

There is 34G physical memory in the server but swap usage keeps creeping 
up, could this possibly be a leak? After startup, it kept putting memory 
in Inactive until it plateaued at 29G as swap usage then started rising.
