This option specifies the path name of the file to which the server
appends statistics when it receives a SIGILL signal. If the path
name of the file is not specified, the default file used is named.stats.
Boolean Options
• auth-nxdomain yes_or_no;
If auth-nxdomain is set to yes, the AA bit is always set on
NXDOMAIN responses even though the server is not authoritative.
The default value is yes. By turning off auth-nxdomain, you can
experience problems with the previous versions of the software.
• deallocate-on-exit yes_or_no;
If deallocate-on-exit is set to yes, the server deallocates all the
objects it has allocated and writes a memory usage report to the file
specified by the memstatistics-file, on exiting. The default value
is no because the operating system deallocates objects faster than
the server. However, you can use the deallocate-on-exit option to
detect memory leaks.
• fake-iquery yes_or_no;
If fake-iquery is set to yes, the server simulates the obsolete DNS
query type IQUERY. The default value is no.
• fetch-glue yes_or_no;
If fetch-glue is set to yes (the default) the server fetches the glue
resource records, that it does not posses, while constructing the
additional data section of a response. You can use fetch-glue no
with recursion no to prevent the server’s cache from increasing in
size or getting corrupted (at the cost of requiring more work from the
client).
• host-statistics yes_or_no;
If host-statistics is set to yes, then, for every host that the
nameserver interacts with, the statistics is maintained. The default
value is no. Note that, setting host-statistics to yes consumes lot
of memory space.
• multiple-cnames yes_or_no;
If multiple-cnames is set to yes, then multiple CNAME resource
records are allowed for a domain name. The default value is no. HP
recommends you not to allow multiple CNAME records for a domain
name as it is against the standard. Multiple CNAME support is
