I'm using apache (with mod_wsgi and django), and everything works fine, except rather strangely once per week apache seems to shutdown, and I have to login to the server to restart it to get my sites back up.
Each week this happens at around 06:30-06:45 Sun or Mon morning. The apache error logs for a given site just show:
#/var/log/apache2/error.log [Mon Aug 18 06:30:01.564916 2014] [mpm_event:notice] [pid 5576:tid 140263321876352] AH00493: SIGUSR1 received. Doing graceful restart [Mon Aug 18 06:30:02.473446 2014] [core:notice] [pid 5576] AH00060: seg fault or similar nasty error detected in the parent process
#/srv/apache/log/error-ssl.log (site specific `ErrorLog` set in vhost) [Sun Jul 27 06:42:47.610600 2014] [:info] [pid 3712:tid 140600110684032] mod_wsgi (pid=3712): Shutdown requested 'mysite.co.uk'. [Sun Jul 27 06:42:47.610706 2014] [:info] [pid 3712:tid 140600110684032] mod_wsgi (pid=3712): Stopping process 'mysite.co.uk'. .
At first I thought maybe a weekley cron job, but I see nothing in
/var/log/syslog that looks like an obvious candidate for causing the conflict.
Does anyone know what this could be or could provide steps I can take to further debug the error?
