      @troye-johnson This is an interesting one. Take a peek at the apache error log in /var/log/httpd.

      Go to the management console to get the 500 error and then just tail the error log file and see what apache isn’t happy with.

          @greg-plamondon OK let me update my dev box (its still on 1.5.0) to see if I can find anything.

                That kind of tells me that php-fpm was enabled and its having an issue. What OS do you have Greg? My dev box is centos so I should be able to duplicate Troye’s issue.

                I wasn’t aware that the devs enabled php-fpm (which is generally a good thing to have running).

                    (still waiting for my dev server to update)
                    I did do some testing for php-fpm a while ago: https://forums.fogproject.org/topic/10717/can-php-fpm-make-fog-web-gui-fast

                    The idea of php-fpm is a dedicated php engine that executes much faster than the built in php engine in apache.

                      @george1421 ok not related to php-fpm.

                      How many client computers do you guys have on your campus?

                          Did you purposely put 10fogserver in there?

                            @george1421 OK I’m back hunting php-fpm timeout.

                            0_1523472558752_phpfpm.png

                            For those with the error can you review this log file to see if it gives us any clue to why /var/log/php-fpm/www-error.log

                              I followed your FPM/FastCGI howto you linked and the problem seems to be gone and considerably faster now.
                              Thanks!

                                    Its great we have php-fpm running, it does make quite a difference, but we need to understand why. I can’t seem to make it fail on my side, but I only have a handful of systems on my dev box.

                                        @greg-plamondon Ok it looks like an upper memory limit got us. OK lets see what we need to do to fix. @Troye-Johnson since Greg already tainted his system hold off for a minute updating yours so we can see if we can fix this memory issue.

                                        Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!
