Alright, so following the README sticky, turn the cacti logging level to debug for a cycle and see what it's timing out on. Debug mode is the only way to reveal what cacti is actually doing to generate that error.

You could possibly look in the poller cache for either of those...

Do you have an invalid rra file path maybe?
