    Ok.

    I've tried this on two servers, one running latest BETA Version of CentMin, and one running the latest stable version.

    Both of the versions are getting 502 Gateaway error when using "Contact Us" under XenForo. As well as registering (when it sends mail I guess).

    One server is hosted with OVH, and have 8 Cores * 3.4 GHz, 2GB Ram & 100 GB HDD.
    The second server is hosted with BuyVM, have 4 Cores * 2.0 GHz, 1GB Ram and 100 GB SSD.

    Both servers are having exactly same issue with XenForo. Both of the installations have no firewall, and both of the installations also get the following php-fpm error:

    Code:

    Full VPS specs ? Other php scripts besides Xenforo running ? what specifically ?

    On Centmin Mod .08 beta03 one, type in SSH the command cminfo and copy and paste info into CODE wrap tag here (rename or mask any domain or databases you don't want to make public)

    Code:
    cminfo
    However, Centmin Mod is provide as is, so short of scripted related bugs or issues, any further optimisation to the web stack components - nginx, php-fpm, mariadb mysql, csf firewall etc or web app specific configurations are left to the Centmin Mod user to deal with. So I do not provide any free support for such. The problem you have is PHP is segfaulting so need to troubleshoot it as outlined here and here.

    However, Centmin Mod users are free to help each other out and ask questions or give answers on this community forum. My hopes are that this community forum evolves so that more veteran long time Centmin Mod users help new Centmin Mod users out :)

    due to php segfault crashing php so nginx can't connect see good explanation at php - nginx errors "recv() failed (104: Connection reset by peer) while reading response header from upstream" - Server Fault

    as to postfix, you haven't properly configured your domain and server for PTR reverse lookups so some mailservers reject your emails. So talk with your web host or domain registrar/dns provider and get PTR reverse lookup properly set so main server IP address has PTR lookup to your main server hostname . Buyvm I know has in their Stallion control panel PTR option for you

    As you're using Xenforo, might as well try upgrading from PHP 5.4 to 5.6.10 via centmin.sh menu option 5 with Zend Opcache enabled (answer yes when prompted). Could be PHP 5.4.40 and 5.4.42 that you're using.

    You on .07 stable or upgraded to .08 beta03 on both ?
