I am running xntpd on NCR System 3000's utilizing UNIX System V.4. In
my current configuration I have 40-50 stratum 4 systems which
synchronize to the same 3 stratum 3 servers. With this setup, the
servers drop many packets causing them to become unreachable to the
stratum 4 systems. See as follows:
server1 server2 server3
xntpdc> iostats
time since reset: 17740 17044 16512
total receive buffers: 25 30 20
free receive buffers: 24 29 19
used receive buffers: 0 0 0
low water refills: 3 4 2
dropped packets: 5892 5186 6412
ignored packets: 0 0 0
received packets: 3191 3973 2494
packets sent: 3817 4125 2756
packets not sent: 0 0 0
interrupts handled: 3131 3803 2446
received by interrupt: 9083 9159 8906
The stratum 4 systems poll every 64 seconds when a server is
reachable.
Are 40-50 pollers too many for a server to process?
Is the poll value of 64 seconds to small?
Is my problem elsewhere?
Thanks for any assistance!
