xymonproxy messages getting truncated
I'm have several xymonproxy servers (over the other side of the world) which send data to my main xymon server. The trouble is that the data received by the xymon server is sometimes getting truncated, and thus it reports false red alerts - usually with procs. The xymon server itself does NOT report that it's getting truncated messages, and nor does the xymonproxy.
I suspect that the network connection between the proxy and the main server is being dropped and some of the data is being lost, but the failed data is not being resent.
Has anyone got any ideas what can be done about this please? I'm getting fed up with alerts saying that my servers are running no procs at all when they blatantly are :).
Cheers, Heather
One thing I have noticed is that when this happens my main server often shows "Multi-source statuses" for the affected clients - showing "procs: reported by <client IP> and <proxy server IP>", whereas when its working properly it doesn't.
Any ideas anyone?

You sure you're not running into the max message size (which I recall was 32k but that could be what I changed it to)? It's configurable somewhere obvious (I believe server-side).

I had problems with the message size due to many connections in netstat and processes in ps. I added the following 3 lines to xymonserver.cfg:
MAXMSG_STATUS="3145728" MAXMSG_CLIENT="3145728" MAXMSG_DATA="3145728"
