[collectd] High CPU usage of collectd when server is under load

[XANi]

Hi,

I've installed collectd on server (amd64 debian stable) and when I have
high load collectd can eat like 90-100% of one CPU (and its not
iowait, disk is fine), what can be reason of that ? my enabled modules
are:

LoadPlugin syslog
LoadPlugin cpu
LoadPlugin df
LoadPlugin disk
LoadPlugin entropy
LoadPlugin interface
LoadPlugin iptables
LoadPlugin irq
LoadPlugin load
LoadPlugin memory
LoadPlugin mysql
LoadPlugin nginx
LoadPlugin processes
LoadPlugin rrdtool
LoadPlugin swap
LoadPlugin tcpconns
LoadPlugin uptime
LoadPlugin vmem

most of them are in pretty much default config, only rrdtool have

       RRARows 12000
       CacheTimeout 600
       CacheFlush   1200
       RandomTimeout 100

What can be reason of such high load ? Collectd works normal (barely 1%
load) when ther is light/no load on server

Regards
Mariusz
