My server Ubuntu 18.04 LTS is creating millions of sess_* files. As per some old threads this problem is fixed but I am using ISPConfig 3.2.11p2 and still having these files occupying almost all inodes. Please suggest any fix?
These files are not from ISPConfig; ISPConfig does not create any sess_* files as it uses database-based sessions. ISPConfig just cleans up old session files in case your website and PHP fail to do it on their own. The question is how old these files are, as ISPConfig will clean up old files only not to remove active user sessions of your site.
