I have an Ubuntu server with zoneminder installed. I only have one camera (cheap Logitech USB model) and it seems to be permanently idle.

I'm also getting this error repeatedly in the logs

06/06/2010 08:26:56.563783 zmwatch[28234].INF [Restarting capture daemon for main_room, shared memory not valid]

I've already tried following the instructions in the FAQ for increasing shared memory, but that doesn't seem to work. What do I need to do to get this working?

Note: I have tested the camera with Linux via Cheese, and that works fine.

Can you post your Zoneminder camera config, sysctl kernel.shmmax output and lsusb -v output relevant to camera? Let the pastebin help you. – whitequark Jun 14 '10 at 13:22

This isn't really an answer, but maybe trying Motion and seeing if that works could reveal some more information that might help you zoom in on the problem?
