DHCP works but the service keeps stopping every few hours
 
Ubuntu 9.10 2.6.31-17-generic
ISC DHCPd version 3.1.2

The DHCP service starts fine on boot and with manual start then works fine for about 4-5 hours. After that it just stops on its own. I start the service up and everything works fine for about 4-5 more hours untul it stops again.

What do I need to do to ensure that the service will stay uo 24x7x365?

Thanks
Mike

Look at your server logs to see why it crashes for a start. If you can't see anything, you can try running the server in a debugging foreground mode for extra output.

You can just stop it and start from console, and see what will be an output.

Below is my /var/log/messages output for " cat /var/log/messages | grep dhcp "

As you can see it just stops with no notification. I've sifted through the raw data for the messages files cnd cant see what may be causing it. I checked cron jobs too and cat see anything that would be stopping it there either.

Also as you can see I started it up just a little bit ago with no errors.
