"synchronisation lost" errors for Solaris NTP server

Hi,

This is Solaris 9, which is service as NTP server for many unix clients. At backend, it it synching time with three GPS clocks. From past few days, I am noticing time reset to 1 second. Is this a problem ?
I was assuming that if it is a network issue or GPS clock connectivity issue, it should lost sync only with one device. But I see, it is saying "synchronisation lost" for all three devices.

Code:
ntp-serv10 # ntpq -p
     remote           refid      st t when poll reach   delay   offset    disp

NAME
ntp-wait - Wait for ntpd to stabilize the system clock SYNOPSIS
ntp-wait [-flags] [-flag [value]] [--option-name[[=| ]value]] All arguments must be options. DESCRIPTION
ntp-wait will send at most num-tries queries to ntpd(8), sleeping for secs-between-tries after each status return that says ntpd(8) has not yet produced a synchronized and stable system clock. ntp-wait will do this quietly, unless the -v flag is provided. This can be useful at boot time, to delay the boot sequence until after ntpd -g has set the time. OPTIONS
-n number, --tries=number Number of times to check ntpd. This option takes an integer number as its argument. The default number for this option is: 100 The maximum number of times we will check ntpd to see if it has been able to synchronize and stabilize the system clock. -s secs-between-tries, --sleep=secs-between-tries How long to sleep between tries. This option takes an integer number as its argument. The default secs-between-tries for this option is: 6 We will sleep for secs-between-tries after each query of ntpd that returns "the time is not yet stable". -v, --verbose Be verbose. By default, ntp-wait is silent. With this option, ntp-wait will provide status information. -?, --help Display usage information and exit. -!, --more-help Pass the extended usage information through a pager. -v [{v|c|n --version [{v|c|n}]}] Output version of program and exit. The default mode is `v', a simple version. The `c' mode will print copyright information and `n' will print the full copyright notice. EXIT STATUS
One of the following exit values will be returned: 0 (EXIT_SUCCESS) Successful program execution. 1 (EXIT_FAILURE) The operation failed or the command syntax was not valid. 70 (EX_SOFTWARE) libopts had an internal operational error.
