php-fpm segfault triyng Network Upgrade on Wordpress

May 23, 2016 1k views
LEMP WordPress CentOS

Click on Wordpress (4.5.2) Network Upgrade results on blank page and the following message: "kernel: php-fpm[xxxx]: segfault at 7ffd2329df08 ip 00007f76c41cc7ca sp 00007ffd2329df00 error 6 in". No core dump related (I tried to enable core dumps with no success). Centos 7 Droplet, LEMP Stack.

Any help is appreciated.

  • Hi @alesalazar,

    Do you use the PCRE module within your PHP installation? If not, try disabling it to see if that fixes the problem. The problem (best guess from the info provided) is that your PHP installation is hitting some or another system limit (see sysctl for memory tuning for the user your wordpress is running as) and segfaulting accordingly. Please let us know as much info as you can on the PHP version, Apache version, and any other related updates you may have recently made.
