Read this: http://distro.ibiblio.org/pub/linux/...cr/daemontools.

Download and install daemontools.

Then follow the instructions here: http://www.linux.com/howtos/Qmail-Cl...WTO/x142.shtml

You could edit /etc/inittab and add a respawn event. Here's an example from my inittab file that makes sure mythbackend is always running for runlevels 2-5:

Code:

mt:2345:respawn:/bin/su - mythtv "/usr/local/bin/mythbackend -l /var/log/mythtv/mythbackend"

There are two other possiblities I know of:

Link: Nagios
This is a network monitoring device that can monitor many services on remote host as well as your local host. You can configure Nagios in conjunction with cron jobs methinks to restart failed services. However, if you're only planning to monitor the local host and not many services across the network, then a tool as powerful tool such as Nagios is overkill and not worth it to you for the time it takes to understand and configure it.

The other option is

Link: Monit
This is also a program that can monitor a host and automatically restart it for you. Unlike Nagios, automatically restarting a failed service seems to be one of Monit's prime directives, while Nagios, though more flexible and powerful, will require some external configuration to get the restarting of services to work.
