Increase your maximum memory to 64mbytes in PHP.INI. Then, perform the following setps in MySQL:

mysql -u root -p cacti
> truncate table poller_output;
> quit;

Then run the following from a command prompt as root at Logging Level of LOW:

php poller.php

You should receive a number of OK's. If not, please post the results of that command. It is likely that PHP just did not have enough memory to retrieve the data from the table that contains the poller results. (poller_output).
