RRD Graphs Stop working

[jsmwalker]

Hi

I've found a few previous threads on this, however nothing seems to be an answer, we are running 1.2-RELEASE
built on Sun Feb 24 17:04:58 EST 2008, and all has been running really well, have been very impressed with the product, however the RRD graphs keep stopping, and can't seem to see any reason, if I stop them and then restart from the Web interface all seems to work again withou a problems for a few hours or a day, but they always stop, from the command line it appears to be running

72091  ??  IN    0:01.59  /bin/sh /var/db/rrd/updaterrd.sh

Anyone any ideas?

Cheers
