Now the error is not sure how this has changed but
NDC command failed : WARNING: key file (/etc/bind/rndc.key) exists, but using default configuration file (/etc/bind/rndc.conf) rndc: ‘freeze’ failed: already frozen WARNING: The zone was already frozen. Someone else may be editing it or it may still be re-loading.
after hitting the Setup RNDC under Bind server in Wirtualmin, at the reboot I receive that similar warning
“WARNING: key file (/etc/rndc.key) exists, but using default configuration…” and some other line regading PID, I didn’t manage to copy
At shutdown command, the system freeze at this warning trying to close the named service.
