Is there a fix for this?
We just upgraded one of our servers from Ubuntu 14.04LTS to 16.04LTS and these started showing up - and with it all clients go purple. This seems to be happening every 30-60 minutes and the only fix is to restart the Xymon server.
Using 4.3.21.
Thanks, John

Hi,
We are getting these errors on 2 xymon servers running 4.3.21 and 4.3.28.
Any steps I can do to debug and/or prevent this error? The only solution is a restart of the xymon daemons.
