MySQL Problem - table poller_ouput

[Lagrange]

I am having the same problem with the latest release of cacti. Once i updated to the newest release every graph i had worked. But a couple of days later, a few have stopped working. I have tried truncating but this doesnt help the ones that stopped. Any ideas?

You did increase memory settings in php.ini? See my signature's link on "NaN Debugging" for more help how to do so
