Log entries explanation

[Jim McAtee]

Can anyone explain the following log entries to me.  What does the
"nonincremental response" entry imply?  Does it have something to do with the
serial number?  Why does the third entry mention the old serial, since the
new serial on Dec 4 would have been 2003120401?
