child pid xxxxx exit signal Segmentation fault (11)

Question

My website keeps crashing and the hosting company have informed that the error sits with an 'Apache'.

Essentially there's loads of lines saying: child pid xxxxx exit signal Segmentation fault (11) At the time of the crash in the apache error log.

Can anyone help with this and advise on a fix / explanation.

Much appreciated

Sadly a segmentation fault can be caused by a whole bunch of things, normally extensions. Are you using mod_php by any chance? — Brandon, Feb 23 '14 at 17:18
Thanks Brandon, I will have to check with my dev team but I think we are. — designandinternet, Feb 23 '14 at 17:20

Check whether your PHP-FPM and PHP versions match. Make sure there is a (correct) PHP-FPM configuration corresponding to your PHP and PHP-FPM version, respectively.

PHP-FPM (config in /etc/php/7.0/fpm) and PHP versions may have gotten out of sync while updating. Updated PHP (/etc/php/7.3/) may cause apache child segfaults because of missing PHP-FPM configuration in /etc/php/7.3/.
