      After editing rc.local and rebooting all i got to web sign in and got this

      Database Schema Installer / Updater
      But i did not get this during set-up to the latest SVN

      I click install and get ’

      Install/Upgrade Successful!
      
      The following errors occured
      
      Update ID: 1 - 0
      
      Database Error:
      
      Too many connections, Message: Check that database is running
      
      Database SQL:
      
      CREATE DATABASE fog
      
      Update ID: 1 - 1
      
      Database Error:
      
      Too many connections, Message: Check that database is running
      
      Database SQL:
      
      CREATE TABLE `fog`.`groupMembers` ( `gmID` int(11) NOT NULL auto_increment, `gmHostID` int(11) NOT NULL, `gmGroupID` int(11) NOT NULL, PRIMARY KEY (`gmID`),
      KEY `new_index` (`gmHostID`),
      KEY `new_index1` (`gmGroupID`) ) ENGINE=MyISAM AUTO_INCREMENT=1 DEFAULT CHARSET=latin1 ROW_FORMAT=DYNAMIC

          @Raymond-Bell are you disabling the services from booting completely? Then using the rc.local?

          THe rc.local won’t work if it can’t stop the original tasking anyway.

          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! Get in contact with me (chat bubble in the top right corner) if you want to join in.

          Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

              I have 11 apache processes running right now, I’m fairly certain it’s normal behavior. Load is under 0.5% total.

                  Can you edit the /etc/mysql/my.cnf file and add in the [mysqld] portion (or change) max_connections = 500 then restart the mysql service? (sudo service mysql restart)

                    Yes that helped with the to many connections
                    Also this helped on the server but not the nodes

                    sudo update-rc.d FOG*service* disable```
                    
                    Try disabling the FOG Services from starting at boot.
                    
                    Then, edit the /etc/rc.local file.
                    
                    Add:
                    
                    sleep 30
                    /etc/init.d/FOGPingHosts stop

                            @Raymond-Bell Did you restart the services after adding the rc.local? I’m sorry if I’m asking obvious questions, but I really just need to make sure. Current update should help alleviate CPU usage as well though.

                                  Something weird. After the new update , my CPU performance from my server was going to 10-20%. After a reboot , he started again @100%

                                  Pretty anoying

                                    I just realized after going through another git pull upgrade that the CPU spike will probably happen every time since the services are reinstalled. Here’s how I fixed my problem again, hopefully in a cleaner way. After upgrading to 6791, it seems to be working so far with a couple reboot tests.

                                    Add this to your rc.local. Adjust sleep time based on your setup. My FOG setup is virtual, so 5 seconds seems to work well.

                                    sleep 5
                                    service FOGImageReplicator restart
                                    service FOGMulticastManager restart
                                    service FOGPingHosts restart
                                    service FOGScheduler restart
                                    service FOGSnapinReplicator restart

                                      @baggar11, @Raymond-Bell I believe I may have fixed this now.

                                      My issue – in theory?

                                      I am moving almost EVERYTHING to static form (where I can). This allows me to get items back without having to initiate a whole class object. The problem, the DB has to be available for FOG to read its info. The services are checking for the item before DB is established. This was totally an over site and for that I’m sorry to all.

                                      With any luck, this issue will be gone now. Please update and let me know.

                                      Thanks.

                                        Why this might affect the CPU? It looks to the DB to get timeout values (and logs). The DB is fully operational, but it’s not initiated by fog meaning the DB is not available. It returns an int of 0 for the sleep time. Put that into an infinite loop, (there’s at least 2 that manage start/restart of the services. It is told to sleep for some period of time already within the looping I’m referring to. However it’s set to 0 (meaning 0 seconds), so it get’s stuck in an infinite loop without ever actually starting.

                                          Just updated to 6795, removed my “restart” lines from rc.local and rebooted. CPU was pegged again. Restarting the services manually brought cpu back down to idle.

                                            @baggar11 as I understand it, this is still potentially due to starting the services before its dependencies have started. This is different from the pegged on update, I think.

                                            Can you simply try reinstall and see if it’s still happening? Or did update always work, only reboot caused these issues?
