Zone Not Updating On Master

[RickWaukCo]

I'm trying to make a change to our internal master DNS server that
servers our internal DNS.  A change was made to the zone file.  The
serial number was updated.  named was stopped and restarted.  However,
when I go to check the change, it didn't take effect.

Here's the top of the zone file:

**********
$TTL 86400
@       IN SOA  dns.waukeshacounty.gov. root.dns.waukeshacounty.gov. (
 2006110302     ; Serial Number (yyyymmddnn)
 7200           ; Refresh Time - 2 Hours
 1800           ; Retry Interval - 30 Minutes
 1209600        ; Expire Interval - 2 Weeks
 86400)         ; TTL - 1 day
**********

However, when I run this dig command against the master:

**********
dig soa waukeshacounty.gov @10.100.0.5
**********

It responds with the following:

**********
; <<>> DiG 9.2.0 <<>> soa waukeshacounty.gov @10.100.0.5

Notice how the serial number in the dig response is older than the
serial number in the zone file.

I have checked the bind logs and don't see anything in there to
indicate any problems with the zone file, but I'm guessing there is a
problem.

Any ideas?  Am I right in that it's probably a typo in the zone file?
What's the easiest way to find the error?  My zone file is huge (~1200
lines) and I'm not the one who typically makes changes to it so it's
hard to say where the typo might be if there is one.

Thanks!
