    Hi everyone,
    Today when try to restarting instance I got this error message:

    [root@vultr ~]# service php-fpm restart
    Gracefully shutting down php-fpm ................................... failed. Use force-exit
    Starting php-fpm [14-Oct-2015 15:29:20] ERROR: unable to bind listening socket for address '127.0.0.1:9000': Address already in use (98)
    [14-Oct-2015 15:29:20] ERROR: FPM initialization failed
    failed

    It works again when restarting the instance, is this RAM related issue?
    Hosted on Vultr.

    Thanks

    sometimes depending on how busy php-fpm processes are it can take some time between stop and restart for php-fpm processes to exit, so port 9000 will still be in use and running

    My VPS (1GB Vultr Chicago) only have 2 brand new sites (wordpress) with no visitor.
    It sometimes it down due to 502 bad gateway

    "no pid file found - php-fpm is not running ?"

    Is this normal?

    IIRC you had alot of problems with initial install and slow downloads/network connectivity on your VPS in the past ? same VPS ? could be other problems as that isn't normal if you have no visitors

    stop php-fpm service and then check if any php-fpm processes are still running.. if they are kill them manually and then start php-fpm
