I have looked at the other BIND 9.5.0 crash dump, and the cause
appears to be different than the one I posted yesterday. This one
happened, as did the other one, after renaming the current query log
and running "reconfig":
mv /var/log/named.query.log ...
returncode=$?
/export/home/named/rndc reconfig
Jul 6 15:59:00 titania named[28558]: [ID 873579 daemon.info]
reloading configuration succeeded
Jul 6 15:59:00 titania named[28558]: [ID 873579 daemon.info]
any newly configured zones are now loaded
For some unknown reason, our monitor script was not running, so BIND
was not restarted until later in the evening, when we noticed that
BIND was not running. Here is some gdb output from the core file;
note that there are some long lines and lines that contain non-ASCII
characters.
