      I increased max connections in mysql and am getting some responses from the web interface but only partial and extremly slow. I am still getting a MaxRequestWorkers error so I will try increasing that some more but I think there is an underlying issue I am just kludging around by throwing resources at it.

      RTFM

          @Joseph-Hales Have you rebooted the fog server? Try to restart MySQL? Restart httpd (apache) ?

            Yes every time I have changed one of the settings in apache or mysql I have first restarted both services and if it still fails I reboot the entire server same result.

              @Joseph-Hales Try to turn down your check-in time even further?

                Where can I change that outside of the web interface. Also this just cropped up suddenly when I updated SVN from 4700 to 4928 and up no other changes the only reason I updated SVN at all at this point is to fix a known issue with new and updated snapins.

                RTFM

                  Ignore the second circle, that’s for reboot/shutdown wait time.

                    The web interface is not responding that is the whole issue so I am unable to access that setting.

                      @Joseph-Hales Oh duh I’m sorry. Do it via CLI then.

                      mysql
use fog
update globalSettings set settingValue = 300 where settingKey = 'FOG_Service_Checkin_Time';

                        Thank you now my web interface is responding did a recent SVN reset this value?

                          @Joseph-Hales I have no idea, but I seriously doubt the @Developers would write any code that would intentionally change your settings.

                          Is it possible that the installer updates this field to the default I wonder?

                            I spoke too soon after a few moments it stopped responding but I am not seeing any new errors in the apache log this time. I will try restarting the server itself instead of just the service.

                                    @Joseph-Hales How many cores does this server have? How much RAM? What’s the core speed? Is the storage SSD or mechanical?

                                    I’m not sure how it’s possible for MySQL to use 139% of a CPU… 😕

                                            had to delete some of the errors as the post kept getting marked as spam by the filter but they seem to be repeats.
