Ubuntu LTS: [fastcgi:error] FastCGI: incomplete headers (0 bytes) received from server "/var/lib/apache2/fastcgi/php5-fcgi-smoice.com-ssl

  • Hello,


    on a server we have a problem with one vhost:


    suddenly it dies. But only this one specific vhost.


    Error is this: [Mon Oct 05 08:56:24.742854 2015] [fastcgi:error] [pid 28387:tid 140471629473536] [client 217.9.111.41:60341] FastCGI: incomplete headers (0 bytes) received from server "/var/lib/apache2/fastcgi/php5-fcgi-smoice.com-ssl"


    All other pools are working.


    It is a wordpress page.


    Distro:


    DISTRIB_DESCRIPTION="Ubuntu 14.04.3 LTS"
    Kernel: Linux ispcp 3.13.0-63-generic #103-Ubuntu SMP


    When i restart php-fpm it works again....


    Any idea what i can fix ?


    Many thanks.


    Best wishes


    Niels
