Re: [rrd-users] rrdcached communication via socket.

I am also having this error, not from RRDs::update, but by the flush from rrdcached (that occurs from time to time, through -w option): queue_thread_main: rrd_update_r (...file.rrd) failed with status -1. (...file.rrd: expected 4 data source readings (got 2)) The only problem is with flushin
