bind 9.5 on Solaris dies silently

[Lars Hecking]

Hi all,

I have made the observation that named sometimes dies silently when I look
at the stats web page. Pretty much full logging is enabled, except query
logging, but nothing at all is logged in this situation. How could I
possibly debug this?

statistics-channels {
inet * port 8080 allow { ACL; };
};

Solaris 9
Bind 9.5.2 compiled on Solaris 8 with
configure --prefix=/usr --with-openssl=/usr/local/ssl --enable-ipv6
--localstatedir=/var --sysconfdir=/var/named

Hi Lars,

If it is silent death at specific time (look at the stats web page) then
why not to "truss" the daemon? Btw. no core file on the system?

Best regards,

Milan

Thank you (and Andrew) for the suggestion. Unfortunately, the problem
seems to be intermittent and I cannot reproduce it at will. I've been
bombarding the stats server with wget for hours no, and named is still
running. No core files.

Will keep trying this for a few days.

It's official: I cannot reproduce this behaviour anymore. The only change
I can think of is that I reinstalled bind on this machine and replaced it
with a version compiled with EXT_CFLAGS="-DISC_SOCKET_MAXEVENTS=128".
