[collectd] uc_insert: Value too old

[Pavel Georgiev]

I keep getting these in syslog on the node that is collecting the data with 
iptables:

uc_insert: Value too old: name = r 
host/iptables-mangle-POSTROUTING/ipt_packets-POP3 Outgoing ALL; value time = 
12
16719524; last cache update = 1216719524;


Is this harmfull or its just because the counters have not increased? Can I 
disable it?

Collectd 4.3.0-1 (binary install on Ubuntu 8.04)
