Thanks for reporting this and sorry for the slow reply :-/ This issue is related to how the rrdcached client library works. It only supports a single connection and caches that in a global variable. collectd calls rrdc_connect on each write but the function will simple return success if it succeeded previously. I think what we'll have to do is (a) in collectd, close the connection on error and, thus, trigger an actual reconnect; possibly use exponential back-off (b) improve the RRDtool API ;-) Cheers, Sebastian -- Sebastian "tokkee" Harl +++ GnuPG-ID: 0x2F1FFCC7 +++ http://tokkee.org/ Those who would give up Essential Liberty to purchase a little Temporary Safety, deserve neither Liberty nor Safety. -- Benjamin Franklin
