The "command channel" error isn't as important as the "pid file" error --
at most, it means you won't be able to control the daemon using the
"ndc" utility.
You should check the permissions of /var/run/named.pid and intermediate
directories. Looks like whatever user you're running named as cannot
write to the file/directory.
