[collectd] rrdc_update failed with status -1

[Stian Øvrevåge]

It always works with sockets and never works with network.

So I don't think there is an error with the rrd or polling itself.

Also; tcpdump shows that collectd with connect to rrdcached but does
NOT send ANY
packets when updating and returning thousands of errors. I believe
that the connection handled by collectd is somewhat faulty... I can
connect to rrdcached by telnet and issue commands without problem...

Brgds,
