Ok, thanks.

I'll check the primary, I thought I saw traffic from the 4.3.4 machine, maybe not.

Ah, ha! Right, the test server has rrd 1.4.5, I don't have that on the proxy.

Don't think so. There has only been two changes in the proxy code going
from 4.2.3 -> 4.3.4:

a) the proxy will no longer forward "page" messages as sent by old (Big
Brother style) clients - Xymon doesn't use these at all.

b) the "--hobbitd" option has been removed; xymonproxy always assumes
it
is sending data to a Xymon server, so it re-packages combo-messages and
adds information about what proxy the message passed through.

I don't see either of these changes breaking compatibility with a 4.2.x
server. On the old Hobbit server, do you see any connections from the
proxy (check with netstat) ? Does the proxy log show that it is sending
data to the old server ?
I also just found some other information, on the 4.3.4 in the log
files:
2011-08-24 14:20:52 Peer not up, flushing message queue
xymond_rrd: error while loading shared libraries: librrd.so.4: cannot
open shared object file: No such file or directory
The rrdtool libraries are missing from the server where you are running
Xymon, or at least xymond_rrd cannot find them. My guess is that you've
compiled the Xymon server software on another system than where you are
running it. Make sure you have rrdtool installed, with the same major
version as you had on the system where it was compiled.
