[Xymon] Spurious purple messages

What do the client hosts share in common?
I have seen in the past, a client was overloading their storage system, and
were overflowing buffers and exceeding the storage array's ability to
process IO requests. Of course this caused a general disk latency, which
slowed things down to the point of a purple flood.
Was no simple solution to that one, except buy more storage, which they did.
Also, check the "serial numbers" on the messages. Is this a repeat of an
older message - in which case Xymon might have something fishy going on, or
are they new messages every day, as in it really thinks there is a problem.
Xymon only updates pages every 2 and 5 minutes, depending on the page you
are looking at. Meaning you could wait up to 7 minutes for the real status
A purple takes 30 minutes to trigger.
With some unfortunate, and highly improbable timing on whatever is
triggering these events, it's possible you might not see the purple.
Have you pulled up a "snapshot report" for the exact time of the messages?
Something else unlikely, but possible, is the network.
The conn test used ping, which is UDP
The Xymon agent sends using TCP.
Is there anything interesting happening on the network at the time?
