Hi,
i had the same error a few weeks ago and guess that the user rrdcached
is running under (usually rrdcached) has no write permission to the rrd
files.

Hi,
I have updated my configuration as following:
LoadPlugin rrdcached
<Plugin rrdcached>
DaemonAddress "unix:/tmp/rrdcached.sock"
DataDir "/opt/collectd/var/lib/collectd"
CreateFiles true
CollectStatistics false
</Plugin>
The rrdcached start script is as following:
rrdcached -F -b /opt/collectd/var/lib/collectd -j
/root/tools/rrdcached/cached -p /root/tools/rrdcached/rrdcached.pid
-l unix:/tmp/rrdcached.sock -l 10.74.125.141
Now the log is as following:

You don't need both rrdtool and rrdcached plugin.

Hi,
I try to setup rrdcached and collectd in one VM(Redhat 6.2).
rrdcached also listens on the network port for remote query.
rrdtool: 1.4.7
collectd: 5.2.0
The collectd.conf is as following:
LoadPlugin rrdcached
LoadPlugin rrdtool
<Plugin rrdcached>
DaemonAddress "unix:/tmp/rrdcached.sock"
DataDir "/root/tools/rrdcached"
CreateFiles true
</Plugin>
<Plugin rrdtool>
DataDir "/opt/collectd/var/lib/collectd"
</Plugin>
The rrdcached start script is as following:
rrdcached -F -b /root/tools/rrdcached -j /root/tools/rrdcached/cached
-p /root/tools/rrdcached/rrdcached.pid -l unix:/tmp/rrdcached.sock -l
10.74.125.141
But the collectd log always show the error:
[2013-03-04 21:24:56] rrdcached plugin: rrdc_update
(/root/tools/rrdcached/10.74.125.141/memory/memory-used.rrd,

I have gone through the old threads and have tried "chmod 777
/root/tools/rrdcached". But it doesn't work.
What is the problem?
