I'm not sure to stop this, but it is becoming an epidemic for all of our hosts. The message is clearly being mis-parsed, restarting the client send a clean disk message. I have a very large message size allowed and I'm not getting warnings about messages over the limit.

You are running a Xymon version older than 4.3.4. Please upgrade - this is a known bug in all 4.3.x versions before 4.3.4.

From the Changes file:

Changes from 4.3.3 -> 4.3.4 (1 Aug 2011)
