Yes. Your clients try to talk to server1, eventually timeout, then deliver to server2. I think the server reads the clients clock time from the status message, so if the message is delayed, the clock time looks wrong.
That's a guess, I haven't looked at the source, but that would explain what you're seeing.

Actually I don’t have this setting in the servers at all just on the
clients.
So xymonserver2 doesn’t know xymonserver1, more than as a client

Could that be due to waiting for the first server to time out when it's
down?

Yes, both xymonservers sync with xntp from the same source, clients sync
from the same source as well.
I have manually checked time on the xymonserver and xymonclients and they are on the dot the same time.

Well, the obvious explanation would be that the clock on your two Xymon servers differ, so on the first server the time is within the clients' idea of what time it is, but on the other server it is more than 10 secs apart.
Have you checked the clock on your servers ?

Hi,
Xymon version 4.3.10
I have 2 identical xymon servers and specify this in the xymonclient.cfg.
XYMSRV="0.0.0.0" # IP address of the Xymon server
XYMSERVERS="192.168.10.1 192.168.10.2" # IP of multiple Xymon servers. XYMSRV must be "0.0.0.0".
If the first mentioned server 192.168.10.1 goes down the second happily just continues and clients sends data to the second one.
But, it will display the cpu on each client as yellow with "System clock is 47 seconds off (max 10)"
Strange enough it is always 47 seconds on ALL clients.
If I swap the ip's around XYMSERVERS="192.168.10.2 192.168.10.1" it goes green again with no time difference.
I can reproduce this any time and it is always 47 seconds.
Is this a bug? or expected behaviour.
Cheers,
