Well, you've thrown a half dozen variables into the mix, including how 
you copy records out of the history file and how you do your 
conversions.  But assuming everything is copacetic, then what you're 
describing is having multiple CPF1164s for one CPF1124.  That's highly 
unlikely so what I suggest you do is dump the the timestamps of the 
multiples, then use that to go back against the QHST file to find the 
matching messages.  Print the actual messages from the log which have 
produced the single CPF1124 and the multiple CPF1164s.

One of two things: you have multiple CPF1164s, or your program is 
incorrectly identifying some records.  I'll be interested to know the 
answer.
