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>

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

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?

Thanks.
Yuantai
