Did you work this out David? I'm seeing the same thing on a test collectd 5.4.1 server I've just set up.
The server is busy (>500 packets per second arriving on it) and there are heaps of these errors being logged. Anyone got any ideas? Eg: Mar 17 22:01:31collectd-03 collectd[16278]: uc_update: Value too old: name = foo.example/snmp/if_packets-FastEthernet0_22; value time = 1395054090.000; last cache update = 1395054090.000; Mar 17 22:01:31collectd-03 collectd[16278]: Filter subsystem: Built-in target `write': Dispatching value to all write plugins failed with status -1. I am using the v5 upgrade target. All the clients are version 4 of collectd, or SSC Serv.
