      I can still WebMin into the box so I could definitely back up everything. Plus I’ve got Samba running so I can easily grab the images. However, this is the second time this has happened. I’d rather find the root cause instead of re-installing (or going back to a snapshot if I virtualize) if this happens again.

        First,

        what’s in the error logs?

        As you’re running 12.04 and Ubuntu, can you check if there’s a permissions error in the /var/lib/php5/sessions folder?

        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)

          Not sure what I’m looking for but I’ve attached a screenshot.

            Look at Tom’s signature. It says where everything is.

              I attached both my Apache error and access logs in a previous post. Do you see anything in them that would indicate a problem?

              As you can see from the screen shot in my last post there isn’t a sessions folder in /var/lib/php5/, only a bunch of files (session files?). Is that a problem?

                Session filenames look alright I’d say. But why are there three files owned by root I wonder AND why are all these files of zero size? Is that really the case? Please run ‘ls -al /var/lib/php5’ on the console on the FOG server. Check the permissions.

                Can’t see any related error in the log files you posted (doesn’t mean much)!

                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)

                  Also,

                  Check the file space:

                    Here’s the results of ‘ls -al /var/lib/php5’ from a copy of those files I made before cleaning out the /var/lib/php5 directory and restarting Apache.

                          Tried that once from Webmin; just did it again from the terminal. Still seeing the same behavior.

                          The restart command returned the following:

                                    Don’t know if it’s just a coincidence but both times this has happened (on two separate installations) I was changing settings on the FOG configuration page at /fog/management/index.php?node=about&sub=settings. Once it was AD settings and the other it was TFTP settings. As soon as I hit the “Save Changes” button it booted me back to the sign in page and from that point I could never sign back in.

                                          Additional info:

                                          I’m able to login to phpMyadmin on this server and it appears to be generating PHP session files without a problem:

                                            Hmmm, that’s interesting. So it’s FOG not being able to save session information properly. Not sure if this is related but someone had issues with wordpress writing zero size session files: [url]http://quirm.net/forum/topic.php?id=3950[/url]
                                            So far I couldn’t really see what was fixing the issue for him. But maybe this can lead us to where we should have a closer look…

                                            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
