Hello -
I am experiencing a situation where apache core dumps. We are using HTML-Mason. The relevant revision numbers are:
Apache_1.3.12
mod_perl-1.24
perl-5.6.0
HTML-Mason .87
redhat 6.1 (no patches)
Our apache server is built in 2 flavors, one that uses Mason, another that doesn but uses mod_perl.
httpd-mason -l reveals
Compiled-in modules:
http_core.c
mod_log_config.c
mod_mime.c
mod_rewrite.c
mod_access.c
mod_setenvif.c
mod_perl.c
whereas httpd-soap (straight mod_perl, but it is used to answer SOAP requests via SOAP.pm)
http_core.c
mod_log_config.c
mod_mime.c
mod_rewrite.c
mod_access.c
mod_setenvif.c
mod_perl.c
Running a barebonse component (nothing tricky, just loads a normal html component) under Mason causes apache to core dump after a few dozen requests. A stack trace reveals:
eading symbols from /lib/libnss_nis.so.2...done.

I've tried building perl and apache and mod_perl with debugging turned on. I can't seem to get more out of the core dump than this.
My point in listing the 2 flavors of our apache configurations is that httpd-soap does *not* core whereas the mason server does.
Normally I'd just try upgrading but I've hit the latest releases of each piece it seems.
I don't know if this will shed any details as to what the problem is.
Any help is appreciated.
Shane
