[cacti-user] Graphs no longer displaying

Morning people,

	I am having a rather strange issue with cacti. I had to reboot the 
server that cacti runs on for maintenance, and ever since the reboot, 
the graphs are no longer displaying. This seems due to the fact that the 
rrd files are not being updated.


	I have checked the poller.log, and i am getting many of these messages

11:15:34 cactus01:$ tail poller.log
06/27/2006 10:39:58 AM - POLLER: Poller[0] Maximum runtime of 296 
seconds exceeded. Exiting.
sh: -: command not found

06/27/2006 11:14:58 AM - POLLER: Poller[0] Maximum runtime of 296 
seconds exceeded. Exiting.
sh: -: command not found


	Now, I saw that some of my hosts were unreachable, and i thought that 
this could be contributing to the timeout, so I removed these hosts and 
still i get these error messages.

	Is there any kind of debug I can set on the poller so I can see where 
the script is getting stuck?

Cheers

Iain
