are you positive the traffic arrives at the right location then? Some
network equipment (tries to do /) does weird "state full" stuff to UDP
traffic..

Can you check with `tcpdump -p $OPTS udp port 3333' if the traffic is
received at the right box.

Please also check if the daemon has actually opened the correct port.
Under GNU/Linux that's done with `netstat -lnp | grep collectd' or,
better yet, `lsof -p $PID_OF_COLLECTD'.

Does your fallback write on a shared storage? If so, are their clocks
synchronized?

Actually, the more details the better ;)

When no graphs are updated, can you see any messages in the logfile on
the server?

Sorry I'm questioning your network setup so much, but version 4.6 is
11 months old and so far you're the first to describe this "state full"
behavior of collectd's network plugin.
