Hi All,
We want to use the RRDCached plugin in our collectd environment but we are seeing a lot of errors in syslog from collectd servers (and collectd clients) like the following:

rrdcached plugin: rrdc_update (/var/lib/rrdcached/db/collectd/xxxxxxxxxxx/df/df-root.rrd, [1374097922:0.000000:0.010000:0.050000], 1) failed with status -1.

The error appears to happen for every rrd file

The RRDCached plugin configurations is as follows:

<Plugin rrdcached>
        DaemonAddress "unix:/var/run/rrdcached.sock"
        DataDir "/var/lib/rrdcached/db/collectd"
        CollectStatistics true

<Plugin rrdtool>
        DataDir "/var/lib/rrdcached/db/collectd"
        CacheTimeout 60
        CacheFlush 3600
        WritesPerSecond 1800
        RandomTimeout 30

We do see that the RRD files (at least some or most of them) are being updated (with new timestamps).

Any way to resolve the error?
