[Pdns-users] pdns and libmysqlclient.so of MySQL 4.0.12

[Markus Gebert]

Hi there

I have a problem after upgrading from MySQL 3.23.56 to 4.0.12. Due to
the changes in libmysqlclient.so I've recompiled pdns that seems to be
dynamically linked against that library. After having done that, I
restarted pdns, which seemed to start at first sight, but didn't
respond anymore. Monitor/standalone still works fine, but the problem
occurs when running as daemon and/or with guardian. Look at this:


(standalone)

[root at server1 root]# pdns_server --daemon=no --guardian=no --loglevel=9
Apr 10 18:17:53 This is a standalone pdns
Apr 10 18:17:53 Listening on controlsocket in '/var/run/pdns.controlsocket'
Apr 10 18:17:53 Opened file '/usr/local/etc/pdns.conf' for configuration
[...]
Apr 10 18:17:53 About to create 15 backend threads
Apr 10 18:17:53 gmysql Connection succesful
[...]
Apr 10 18:17:53 gmysql Connection succesful
Apr 10 18:17:54 Done launching threads, ready to distribute questions


(no daemon / with guardian)

[root at server1 root]# pdns_server --daemon=no --guardian=yes --loglevel=9
Apr 10 18:19:11 Listening on controlsocket in '/var/run/pdns.controlsocket'
Apr 10 18:19:11 Guardian is launching an instance
[nothing happens]


(daemon / with guardian)

[root at server1 root]# pdns_server --daemon=yes --guardian=yes --loglevel=9
[root at server1 root]# tail /var/log/messages
[... (other log stuff)]

I guess, the new mysql library causes this, but I'm not sure... why
does it work in standalone mode then? pdns static 2.8 from
www.powerdns.com works without problem... I guess mysql is statically
linked in that case.

Any ideas?
