Re: Bind Error

Hi Darryl and others,

Deeply sorry to all about the html in the e-mail.

You where right about running two copies of bind. I noticed earlier today
that it had stopped responding again, so I done a named.restart, and it did
not close the initial process off, but starting a second process thus giving
the permission denied errors in the log file. This still leaves me with the
inital problem of why it's either closing or crashing etc.

I cannot find any errors in the log file as to why, but I will have a look
in the Google site like you have suggested.

Thanks for your help Darryl
