Hi,
Does anyone have any suggestions on what else I can try to get a core
dump to track down a segmentation fault????
I've tried the various suggestions in the mod_ssl FAQ including:
1) Setting CoreDumpDirectory to /tmp
2) Starting Apache as a non-root user (Apache failed to start because
of privilege problems).
3) Running the child servers as root (Apache refused to start for
security reasons).
4) Starting Apache in single-process mode using httpd -X .
but the segmentation fault fails to produce a core dump.
I'm using Apache/1.3.11 (Unix) PyApache/4.19 mod_ssl/2.5.1 OpenSSL/0.9.5
on Redhat Linux 6.1.
I'm running a single Apache server for both non-SSL and SSL access.
It all works perfectly except that child servers die with (e.g.):
[notice] child pid 3732 exit signal Segmentation fault (11)
under the following conditions which are 100% reproducible:
1) The child server has been used for at least one SSL access.
2) The child server receives a non-SSL CGI POST request ==>
segmentation fault.
CGI GET requests don't have this problem.
OpenSSL was a absolutely standard install.
mm was installed using:
./configure --disable-shared
make
mod_ssl was installed using:
./configure \
--with-apache=../apache_1.3.11 \
--with-ssl=../openssl-0.9.5 \
--with-mm=../mm-1.0.12 \
--prefix=/usr/local/apache \
--disable-rule=SSL_COMPAT \
--enable-rule=SSL_SDBM
cd Apache directory
make
make certificate TYPE=test
make install
httpd -V gives:
