After rebooting the server due to an unexplained freeze, squirrelmail stopped working. Looking into the issue, it appeared that it was unable to save sessions data.
Apparently, /tmp became 755 so php couldn't write session data.
Now, it seems to me that I've inadvertently changed something during the various updates (mysql5/php5/apache2) using ELS/DA before this forced reboot that altered configuration.
Is /tmp where DA configured PHP to use by default or was it some other folder that got changed when I updated php?
Also, I've made it work now by doing a 777 on /tmp but this seems unsafe to me.
Is it ok to leave /tmp at 777 or should I make a folder elsewhere chown it to webapps:webapps?
