[Xymon] Client reports getting muddled up

That's interesting Ralph.  We sometimes get the same issue with client's
status reports getting assigned to the wrong host in the Xymon server too
(and this is just using the normal xymond receiver).  I thought it might be
related to one or two very big message senders though.  It's difficult to
track down and can happen briefly, trigger an alert and vanish into the
mist within a minute when the next report comes in (though some evidence is
left behind in the history).  But perhaps you are getting big message
senders are a reboot as it's sending quite a lot of data in the msg column?

Kind regards,

SebA
