Please Help me!

I have 6 IBM Pseries machine, all OS is AIX 5.3.


I used the ntp protocol in all machines, 2 DB Servers and 4 AP
servers.
The Network port (GBIC only) has been occured, I changed the GBIC
only.
After ntpq print out many clients information, and xntpd of AP
servers
is not syncronized with the time servers.


This is the my ntp protocol configurations.

I think that the NTP status of DB1, DB2, AP1 Server is nomalcy.
But the AP1 Server has some problems.
"ntpq" command of AP2 Server print out the many client informations.
That informations is reached 1024 lines, "ntpq" command print out the
error messages,
and "ntpq"command is stopped.
<--------------------------------------------------------------------------­-------------------------------------------------------------



Error Messages
***Buffer size exceeded for returned data
<--------------------------------------------------------------------------­-------------------------------------------------------------



Questions :
1) Why do the AP1 Server printed that messages of client information?
2) Is that correctly printing the informations of clients?
3) How can I disappear the clients infomations?
- I have been tried to change the ntp.conf of AP1 Server by various
means.

Have a good day.
