Graphs have stopped

[shagz]

Just noticed all my graphs have stopped. Did a lil research and it looks like my poller is not working correctly. Below are the symptoms.

OS: Ubuntu

I cleared the cacti.log just incase the log was to full, logged into the shell and manually started the poller.php this is what I recieve

01/31/2007 04:39:20 PM - POLLER: Poller[0] DEBUG: About to Spawn a Remote Process [CMD: /usr/bin/php, ARGS: -q /usr/share/cacti/site/cmd.php 0 31]
Waiting on 1/1 pollers.
Waiting on 1/1 pollers.
Waiting on 1/1 pollers.

this keeps going and finally ends with this


01/31/2007 04:45:46 PM - POLLER: Poller[0] Maximum runtime of 292 seconds exceeded. Exiting.

Warning: pclose(): 54 is not a valid stream resource in /usr/share/cacti/site/lib/rrd.php on line 47

Anyone have any idea what maybe causing this? or more troubleshooting steps to solve this?

Thanks
