There are over 5,000 APRS clients (not including CW stations) that
provide their data to hundreds of servers.  Some of the IGates do dupe
checking (when they are part of a server like aprsD and javAPRSSrvr).
Some server software provide a dupe log, some don't.  None of the "log"
formats are compatible.

Bottom line: focus on the "trouble" system(s).  Talk _directly_ with the
sysop(s).  Diagnose the actual problem.  Correct it.

This is not for the faint of heart.  This takes a little knowledge in
diagnosing network and system issues (gee, why is there a 2 minute delay
when I am running a server on Windows 98, 200 MHz CPU, and 128 meg of
RAM?  I wonder...)  It would be nice if the world was cookie cutter and
everything worked the same.  It isn't.  Nothing does.  APRS and APRS-IS
are a collection of systems and software in all shapes and sizes.  You
aren't going to fix the problems by looking at all of APRS-IS.  You fix
the problems one at a time by working with those directly involved.
