What Happens
If the I/O is issued as the result of a request from a network management application,
DNSCOM, or a remote name exporter, the request is replied to with return code
ZDNS-ERR-IOERR.
The requester should retry the I/O based upon the same criteria as it would if it had
received the I/O error while directly accessing a disk file.
This error is fatal in the following cases:
The I/O error occurred on the DNS configuration file (default is
$SYSTEM.SYSTEM.DNSCONF) during name manager or name exporter startup.
The I/O error occurred on the DNS-QUEUE-FILE during name exporter startup.
The I/O error occurred on the name exporter’s open of the name manager.
