I'm not really the expert in this, but you might want to try removing PerlFreshRestart and Apache::StatINC from your config and see if that helps...

Subject: Segmentation Fault: RedHat 6.[01] / Apache 1.3.12 / mod_perl 1.22 / perl 5.005_03 / IE 5

I'm having a very strange problem.  I'm running a very large application under apache/mod_perl (100+ modules; httpd children grow to 40+MB).  The application uses Apache::DBI (DBD::Oracle) & CGI.pm, so I have it running as a handler and everything works fine.... except... :)

If the first request to httpd comes from IE5 to the web root, the child httpd process will segfault.  However from any other client I've tried ( Netscape Comm. and "telnet 0 80 GET /" it works fine and doesn't segfault.  Even stranger, if I point IE5 at "/perl-status?inc", and then at "/" it doesn't segfault (from that point forward it doesn't segfault; even if it hits a new child httpd).

I haven't been able to isolate the problem because I haven't been able to get apache to give me a core file.  I've tried the "ulimit -c unlimited" without success.  Any hints, RwhatFM, etc????

My build script is attached. (which includes building mod_ssl, but this even happened before I added mod_ssl)

Thanks in advance...
