    @Wayne-Workman I say lets just start by stopping the fog services.

    Restart apache 2 (do not restart the fog services.)

    Considering the main box has a 15 minute load of 120 or more 5 minute of 130 and 1 minute of 150 adjusting the times is not going to help at all.

    sudo service FOGMulticastManager stop
    sudo service FOGImageReplicator stop
    sudo service FOGSnapinReplicator stop
    sudo service FOGScheduler stop
    sudo service FOGPingHosts stop
    sudo service apache2 stop && sleep 60 && sudo service apache2 start
    

    I have it waiting one minute after stopping httpd to give the main server some breathing room. These should be run on the “Main Server” and of course you can run them on the nodes if you want to.

    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)

          @Raymond-Bell Adjust the fields I pointed out earlier, then I’d say reboot.

            @Raymond-Bell For now, I’d say leave the services off until you are sure the load has finally balanced out.

            Then start the services one at a time and watch closely to the load. I don’t think starting them, now, would be a problem, but i’m starting to think you’re seeing conflicting runs due to potentially dual webroot’s acting in place. (Again it’s all theory as I really don’t know.)
            If you wait five minutes between starting the services, it should give you a good base line as to which one (or multiple) are causing issues.

            If you see one service starting to tack up the load, stop it, and go on to the next. If all services do the same we have a baseline to try finding info for/on.

            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 can confirm the 100% cpu usage issue. I don’t have any storage nodes in my setup and have a c2750 based atom processor running my FOG virtual machine. I only have 2 test images, each around 1G.

                I found that when I downgraded to version 6753, the high cpu usage disappeared. 6755, 6757 and up all produced the issue.

                The next git commit has this in the log.

                            I just updated my home FOG setup (which includes many nodes) to r6769 and I cannot replicate the issue. I’m using Fedora 23

                            And my replication setting is set to 60 seconds, and I’ve got the slowest setup in town (running 4 OSs on a single Core 2 duo, and P4s with 100 meg switches).

                            It’s either a Ubuntu thing or a New Client related thing. And I’m leaning towards it being a Ubuntu thing.

                            It’s also possible that there is some certain scenario that happened to cause replication to go awol, but we won’t know until we can see a setup that is affected and figure out what’s going on.

                            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!

                              I was just able to test my 1 fog client system at home. it doesn’t make any difference.

                              I think this is a Ubuntu issue.

                                @Wayne-Workman And all, I made a rather significant change (though outside it shouldn’t matter), to hopefully make an attempt at figuring this out.

                                Basically please try out the latest. First thing I noticed was a very similar result on my storage nodes, (one that is Ubuntu 15, and the other that is Fedora 23) and I found that my particular issue was due to the service sleep time being parsed as a string rather than an integer. This would cause the FOG Services to keep cycling (after initial reboot) probably due to improper connection finding. I’m hoping this is fixed but also a much more performance enhanced FOG server capability.

                                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)

                                  @Tom-Elliott Thanks Tom. Have these changes been pushed to Git too? That’s what I’m using…

                                    @baggar11 Whenever I push, I automatically push to both svn and git. I’m not expecting any miracles though, but would be nice to know if I’m at least kind of on the right track.

                                      I’m still seeing the issue on the newly pushed 6775. ImageReplicator, MulticastManager and SnapinReplicator seem to be taking all of the cpu load at around 31.6%

                                          @Wayne-Workman My screen wrapped in my terminal. The “G” is in fact there when I full screen and grep the ps output again.
