The restart part of this script is buggy and documented as this:

        # Wait for children to finish too if this is a daemon that forks
        # and if the daemon is only ever run from this initscript.
        # If the above conditions are not satisfied then add some other code
        # that waits for the process to drop all resources that could be
        # needed by services started subsequently.  A last resort is to
        # sleep for some time.

This is why we have so many scripts with "sleep". On 138 init.d script I
have on my system, 52 are using sleep. This is full of race
conditions. If your system is slow, a restart will likely fail because
sleep will not wait enough time.
