    So I look into the issue and cannot find a reason for this continual "down" situation.
    I then restart monitoring until the same merry-go-round eventuates.

    I understand that watchdog is only a script that is designed to get a response from a specific port. There is a possibility where 'delay' respond in certain condition on that port may consider as a 'downtime' by watchdog.

    The issue seems to be just that.
    The log shows that that watchdog not able to get a response from httpd (localhost:8443) port at that time.

    There is no excessive load on the server.
    There is no excessive RAM usage.

    Why is this happening and what can I do about it?

    Anything in the daemon's error_log in /var/log/sw-cp-server?

    Do you happen to schedule a Plesk Backup - I receive these notifications every time I run a Plesk Backup as 8443 becomes unavailable for a short time.

    Might be worth looking if you can get Watchdog to output "ps -faux" into the email so you can see what processes are running when the server goes down. (This would be a useful addition to Watchdog anyway!)
