      since updating to 2929 my server load has been steadily climbing throughout the day. I upgraded early yesterday and by this morning the system was unresponsive to tftp and web access and console access was slow. I rebooted and was back to normal but at this point after 6.5 hours up time server load average is 32 to 33 and pages are slow to respond in the web interface.

      RTFM

          ###########################################

          Version: 1.3.0 Installer/Updater

          • Found FOG Settings from previous install at: /opt/fog/.fogsettings
          • Performing upgrade using these settings…

          Starting Debian / Ubuntu / Kubuntu / Edubuntu Installtion.

          #####################################################################

          FOG now has everything it needs to setup your server, but please
          understand that this script will overwrite any setting you may
          have setup for services like DHCP, apache, pxe, tftp, and NFS.

          It is not recommended that you install this on a production system
          as this script modifies many of your system settings.

          This script should be run by the root user on Redhat or with sudo on Ubuntu.

          ** Notice ** Redhat users will need to disable SELinux and iptables in
          order to use FOG
          Please see our wiki for more information at [url]http://www.fogproject.org/wiki[/url]

          Here are the settings FOG will use:
          Base Linux: Debian
          Detected Linux Distribution: Ubuntu
          Installation Type: Normal Server
          Server IP Address: 10.200.10.150
          DHCP router Address:
          DHCP DNS Address: 10.200.10.33
          Interface: bond0
          Using FOG DHCP: 0
          Internationalization: 1
          Image Storage Location: /images
          Donate: 0

               DHCP will NOT be setup but you must setup your
     current DHCP server to use FOG for PXE services.

     On a Linux DHCP server you must set:
         next-server

     On a Windows DHCP server you must set:
         option 066 & 067

       Option 066 is the IP of the FOG Server: (e.g. 10.200.10.150)
       Option 067 is the undionly.kpxe file: (e.g. undionly.kpxe)

                I believe Junk is refering to the PHP Session. cleanup portions.

                    Please help us build the FOG community with everyone involved.

                        why would you have to restart mysql at all?
