What is the mod_wsgi configuration form the Apache configuration file which you are using? Are you using embedded mode or daemon mode?
Version 4.3.0 of mod_wsgi is 15+ releases behind, so somewhat old. That you are using Apache 2.4.10 also concerns me, because if Debian back ported a specific CVE fix from Apache 2.4.11, then it can cause older mod_wsgi versions such as you are using to crash in certain circumstances. Ideally if you could update to the latest mod_wsgi version and see if that helps, would be best. If it still occurs in the latest version, then we can investigate further.
