Hi, I recently found my /tmp folder on Ubuntu 12.04 (web server with ISPConfig 3) is full of sess_ files. Obviously PHP session files, comming from at least one of 500+ hosted web sites. The main question is, how did that happen all of the sudden? I did push some updates of Ubuntu and ISPConfig, but have no idea, how to find out which site is filling up my /tmp folder. Sess_ files themselves give no clue. My web server *should* be setup to use eash site's chrooted /tmp folder for those files, not root's /tmp folder. So at least one site is violating this setup. Any idea, how to find out the problematic site?
