        Increased MaxRequestWorkers from 150 to 500 in mpm_prefork_module
        Hi,

          So no improvement with imagereplicatorglobalenabled off?

          With this issue I’ve increase my client communication up to 30 minutes. I will reduce when I know things have stabilized.

          In Ubuntu, see which mpm you have enabled. There should only be one in /etc/apache2/mods-enabled. That’s the file you would edit to increase the MaxRequestWorkers. Make a copy of the file before editing.

                Oh very thanks it’s works !
                I was thinking test this before but maybe not with “imagereplicatorfogenabled” at off.
                After few minutes cpu is ok.

                Thanks.

                  Hi,

                  Today it’s better but all the 30 minutes we have pic of 2 minutes.

                  In wiki it’s write (https://wiki.fogproject.org/wiki/index.php?title=FOG_Client😞

                  The frequency of the checkin-time determines how quickly the FOG Client will receive instructions from the FOG Server. If an image deployment is scheduled for a computer that is turned on, with a checkin-time of 60 seconds, means the FOG Client may begin initiating the task anywhere from 0 to 60 seconds + the random staggering time that is added. This same concept would apply to immediate power management tasks, snapin tasks, capture tasks, and so on. Scheduled tasks are not affected by this behavior, and if the target system is on when the scheduled task is to be ran, this will happen on time

                  How it’s possible to modify the random staggering range for spread over 10 minutes for example ?

                  Thanks.

                    The staggering is not meant to be adjustable, what’s meant to be adjustable is the FOG_CLIENT_CHECKIN_TIME, this governs how often the FOG Client should check with the server. Assuming 10,000 computers power on all at exactly the same moment, over the course of the day the random staggering will cause all clients to spread out evenly with their check-ins. But nobody has 10,000 systems all powering on at the same second. Generally, organizations either A. leave their computers on all the time or B. allow the end-users to power them on.

                    Also asking @Joe-Schmitt if he could give further explanation.

                    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!

                      1.3.5-RC 10 and working fine.

                      All clients are back on, I’ve already reduced the client check in time, and the load was fine for the start of the school day.

                      The Image replicator service is still off.

                        Hi,
                        Ok i understand.
                        Actually majority off our classroom reboot at the same time for software update in night (same time is residual effect with green fog on old version).
                        I will adjust power management (good amelioration in this version) for spread out this reboot.

                        Thanks.
