Monitor reports PO is unknown every 10 minutes

I've upgraded to GW14.0.2 and since the upgrade GWMonitor reports one PO status as unknown every 10 minutes, 5 minutes later it reports ok.

The Admin console doesn't show any state change at all and users are connected fine, so it just seems to be the monitor.

I can access the PO via it's web console without any problems.

I'd appreciate any suggestions on troubleshooting this.

Thanks
Steve

    Either something is getting in the way of the packets (whether on wire
    or in one of the servers) or one of the agents is having issues.

    - Start with a continuous ping between those servers for a stretch. Are
    any dropped? Does the response time vary much? Try with larger packet
    sizes such as 500 or 1000 bytes.
    - A packet capture on the POA side would help to see if it is receiving
    the Poll packets and see if responses are being made that just don't
    get to the Monitor box in a timely fashion.
    - A test with the firewalls down on both servers would be useful.
    - When you next have a suitable maintenance window, shutting down your
    network switches to fully flush their MAC-Port cache.
    - Confirm that you don't have any duplicate IP addresses or MACs
    - Are any of the NICs in question showing errors? Do they increment
    with the fails? "ifconfig" on SLES, I think "Performance Monitor"
    (perfmon.exe) is the tool on Windows.

    - Does the POA logs show any errors? Either server's system logs?
