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

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