Hello,
I found a strange case on bind server.
when one named was running, I started another one or more (the same) named
server again, they all got started successsfully.
this is the ps output:
nobody 28312 1 0 10:10 ? 00:00:00 /usr/local/bind/sbin/named -u
nobody
nobody 28359 1 0 10:16 ? 00:00:00 /usr/local/bind/sbin/named -u
nobody
nobody 28362 1 0 10:16 ? 00:00:00 /usr/local/bind/sbin/named -u
nobody
But at this time named server behaves not normal.
for example, I added a NS record and execute rndc reload, the new record could
not be queried.
why this happen?
Do you have a wrapper script that checks whether there is already a
named instance running before starting another one?
Starting named manually without some sort of wrapper script like that is
dangerous business, the instances have a high possibility of fighting
with each other over the listen port, with the end result often being
that *none* of them are functional. Look at your logs, you'll probably
find some ugliness there.
