Weekend Learning: Troubleshooting memory leaks for UNIX (Siebel)

Recently I ran across the My Oracle Support article "How To Troubleshoot Memory Leaks on UNIX" in note ID 477522.1 but I was a bit disappointed to find it relating to Siebel application/architecture because I do not know anything about this nor am I aware of us running this software at work.  Why did I still post it then?  Well, this might not be specifically apples to apples for everybody (and if you support Siebel, bonus!) yet I think there are a few general ideas that can be extended for other applications so it is certainly worth a quick review.
