Segmentation fault on certain WordPress pages on Ubuntu / Apache / PHP
I’m getting reproducible errors when trying to access certain parts of a WordPress instance. This identical behavior occurs on two WordPress instances hosted on the same box.
The two actions that fail (and lead to an error page in Chrome (Error code: ERREMPTYRESPONSE), and an error logged on server) are:
- Attempting to access the “General” settings page (/wp-admin/options-general.php)
- Attempting to confirm the deletion of any plugin
[core:notice] [pid 9173] AH00052: child pid 9177 exit signal Segmentation fault (11)
[core:notice] [pid 9173] AH00052: child pid 9181 exit signal Segmentation fault (11)
