monitoring and restarting bind

[Waltner, Steve]

What version of Solaris are your running? What error messages are you
getting? Where did you install your copy of BIND? Without basic info like
this, we can't really help debug the problem. My gut feeling is that you are
running Solaris 2.6 or earlier, which don't include the pgrep command. But
since you didn't include the error message, that's just a WAG.
