[Pdns-users] Crashing 2.9.11

[Marc van de Geijn]

Hi,

I noticed that my PDNS 2.9.10 server was crashing. Upgraded to 2.9.11, but
no change. Anybody an idea what is causing this crash?

I'm not sure the crash is because of it, but I changed the configuration of
the MySQL server PDNS is using. Connections that are not used for more then
120 seconds are closed. Because this PDNS installation is running on a
webserver, I really need this settings to prevent to many connections from
all the websites running on the same MySQL server.

Marc
