Secondary DNS is not updated quickly from Primary

Dear All,
     
DNS Setup: 
1. Primary DNS on Solaris 9 with BIND 9.2.3 ( Solaris package )
2. Secondary DNS is on Solaris 10 with Bind 9.2.4 ( build in of Solaris 10 )
Problem :

1. When i changed "Zone" on "Primary DNS" with updated "Serial no" in Zone
file & then used  "rndc reload / rndc reload 
   <zone name>" on Primary DNS.
   "Secondary DNS" zone is not updated immediately even i kept "refresh rate
as 5 min".(i uses rndc reload on 
    Secondary DNS) but when i uses "rndc reload <zone name>" on "Secondary
DNS" then zone gets transfer immediately.
   Is this bug in BIND 9.2.3? because i had not faced problem with "BIND 8"
for Zone Transfer.   

2. Is any BIND patch available for BIND 9.2.3 on Solaris 9? 

3. If instead of rndc key if i uses tsig key then will security will
increase?

   
Best Regards

The slave should automatically refresh the zone every <refresh> seconds, 
where this is the Refresh parameter in the zone's SOA record.  So if you 
want to ensure that it updates within 15 minutes, set this to 900.

You should also be able to use the DNS Notify mechanism.  Make sure that 
the slaves are listed in the NS records of the zone, and the master will 
send a Notify message to the slaves within a few seconds of your 
reloading the zone on the master.

Of course, make sure you increment the serial number on the master after 
making chances.

Are there any messages in the slave's log when it should be refreshing 
the zone?
