[Pdns-users] 2.9.8 crash: Signal 11?

Tue May 13 22:22:28 UTC 2003

Hi,

Since I'm using 2.9.8 (did a recompile a couple of hours ago, but am using
it for a couple of days) I get these strange crashed from time to time.
Below is a trace of such a crash, which seems to be a couple of crashes in
very short period of time.

What causes a signal 11? Is this a normal signal?

Another question I have is: I'm only using the gmysql backend. The bind,
bind2 and random backends are not used. How can I get these backends out of
the server? Which options do I need to set at compile time?

Kind regards,
Marc
