Version 5.1 is no longer being maintained by IBM; we were some
displeased when we heard when support offerings were expiring :-(.
Fortunately, we already had plans in place for a migration to 5.3.

I have to agree that even 4.3 is "really rather old" now.

Looking at IBM's "support lifecycle" list...
<http://www-306.ibm.com/software/info/supportlifecycle/list/a.html>

AIX version   Available    Support Withdrawn
-----------------------------------------------------------------
  5.1         May 2001      April 2006
  5.2         Oct 2002      Sept 2008
  5.3         Aug 2004      unannounced, presumably late 2010...

I'd guess that 4.3 fell out of support in late 2004.
