We are running debian linux stable (Jessie) with apache 2.4.10 and mod_wsgi 4.3.0-1 on a x86_64 machine. Our application is written in python 2.7 and django 1.8.
The list of modules as reported by apachectl -M are:Loaded Modules: core_module (static) so_module (static) watchdog_module (static) http_module (static) log_config_module (static) logio_module (static) version_module (static) unixd_module (static) access_compat_module (shared) alias_module (shared) auth_basic_module (shared) authn_core_module (shared) authn_file_module (shared) authz_core_module (shared) authz_host_module (shared) authz_user_module (shared) autoindex_module (shared) cgi_module (shared) deflate_module (shared) dir_module (shared) env_module (shared) filter_module (shared) mime_module (shared) mpm_worker_module (shared) negotiation_module (shared) perl_module (shared) rewrite_module (shared) setenvif_module (shared) socache_shmcb_module (shared) status_module (shared) wsgi_module (shared)
We were getting segmentation faults when rest api clients were making requests. The apache error log has the following messages:

I have enabled core dumps by setting ulimit to unlimited and adding core dump config directive in the apache2.conf file.
but the core dumps are not happening. When I tried to debug using gdb (gdb /usr/sbin/apache2), the environment variables are not getting read. Any clues on how to go about this?
