Starting this weekend rrdcached appears to have stopped working correctly. Has anyone seen an issue with this? We've been using it for a long time and it seems to have broken totally early Sat morning (somewhere around 1 to 2 AM)
Running the poller with debug doesn't give me a status any more, and I have hundreds of rrdtool processes being spawned to the point it actually took over most of the disk IO on our NAS on Saturday.
/opt/observium# poller.php -h localhost -m system -dd | grep RRD RRDtool 1.7.0 Copyright by Tobias Oetiker tobi@oetiker.ch RRDCacheD 1.7.0 o RRDtool 1.7.0 (rrdcached 1.7.0: unix:/var/run/rrdcached.sock) RRD PIPE OPEN[TRUE] o RRDTool Usage (0s 0%) RRD PIPE CLOSE[TRUE]

Really need to get this one solved if anyone can offer help.
