[collectd] rrdc_update failed with status -1

[Stian Øvrevåge]

Tried now using

rrdcached -f 7200 -w 3600 -z 900 -b
/opt/collectd/var/lib/collectd/rrd/ -P FLUSH,BATCH,UPDATE,STATS -l
127.0.0.1 -l unix:/tmp/rrdcached.sock

No change tho. No packets after the connection has been established.

Tried simulating using telnet, working just fine:

root at collectd-new:/home/kbandusr# telnet localhost 42217
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
