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...
