      @baggar11 And they’re constantly cycling CPU?

      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!

        @Tom-Elliott Uptime is now at 17 minutes and nothing has changed in CPU cycle regard.

          One thing that I noted was interesting was after an upgrade, cpu cycles are normal. System is idling. FOG WebUI works fine, no issues.

          Once I restart the virtual machine and the FOG services start up on boot, that’s when those 3 services start consuming all of the cpu.

            @baggar11 Well, there’s 5 total services.

            That said, it seems this is somewhat well known about, and our method to “check” and correct isn’t working properly. It only seems, to me, to impact Ubuntu (Maybe older versions of Debian?)

            I know the problem, in the past, was related to the network (maybe other required services) aren’t running when the FOG Services start up.

            Maybe try adding a sleep 30, then manually start the services by the use of the rc.local file.

            Basically the rc.local is processed LAST and by that time, network may still not be up, so the sleep time just ensure’s it has ample time to come up.

            Try disabling the FOG Services from starting at boot.

            Then, edit the /etc/rc.local file.

            Add:

            sleep 30
            /etc/init.d/FOGPingHosts stop
            /etc/init.d/FOGScheduler stop
            /etc/init.d/FOGImageReplicator stop
            /etc/init.d/FOGSnapinReplicator stop
            /etc/init.d/FOGMulticastManager stop
            /etc/init.d/FOGPingHosts start
            /etc/init.d/FOGScheduler start
            /etc/init.d/FOGImageReplicator start
            /etc/init.d/FOGSnapinReplicator start
            /etc/init.d/FOGMulticastManager start
            

            This should put the service files to a point where they’re not constantly looping (which is what’s most likely causing the CPU load in the first place.

              Sorry guys! I have been rolling the dev version for so long without issue, I totally forgot about the startup services possibly being an issue. I’m all set now. Here’s what I did.

              Ran this on each service

              sudo update-rc.d FOG*service* disable
              

              Then, as suggested, added these line to my rc.local

              sleep 5
              service FOG*service* start

                  @Tom-Elliott Upgrade to latest pull r5037
                  server is fine if i start the services one at a time

                  but both storage nodes have high CPU
                  and i have started them one at a time to check
                  as soon as i start one it jumps to like 98% and levels out at about 50%

                      Editing the rc.local file now will let you know after reboot

                            @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.

                            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.

                                      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

                                          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)

                                          Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG
