Hi, I have intermittently a critical alert by mail indicating that root directory "/" is full at 95%, and when I launch the "df-h" command, I found it decreased at around 87%. this is happening at the same time-slot, i'm suspecting some cPanel temporary files that are put somehow in root directory and deleted afterwards. Here is my actual partition : Filesystem Size Used Avail Use% Mounted on /dev/sda2 39G 34G 5G 87% / tmpfs 3.9G 0 3.9G 0% /dev/shm /dev/sda1 969M 61M 858M 7% /boot /dev/sda7 376G 122G 236G 35% /home /dev/sda6 4.7G 2.5G 2.0G 56% /tmp /dev/sda3 29G 18G 9.8G 65% /usr Would you please advice what files could I remove safely in root "/" so I can empty more space ? Thanks in advance.

  Check your old kernel files and eror_logs

  It really depends on what is consuming space in / you would need to identify that first. Typically I do something like the following: cd / du -h --max-depth=1
  And drill down into the directories that are the biggest from there.

  Thanks Lauren, I go throw subfolder and found thoses two files eating ~10G inside /var/cpanel 4746948 eximstats_db.sqlite3 4856236 eximstats_db.sqlite3-wal Are both files required? Is it safe to remove "-wal" or at least move it to another partition ?

  For more info, in tweak settings I set the value : The interval, in days, to retain Exim stats in the database to 1 day.

  Exactly the solution! I'm glad to see you changed that. This will keep the DB size down considerably.

  Thanks Lauren, The actual size is still enormous even if with 1 day exim stat retention: 4754268 eximstats_db.sqlite3 4864868 eximstats_db.sqlite3-wal Did I miss something? Is there a way to reset stats ?

  I agree with you it is really large. To confirm you modified WHM>>Server Configuration>>Tweak Settings -> The interval, in days, to retain Exim stats in the database to 1? How much mail are you sending daily? I keep mine for 10 days and I barely use 7MB - short of not retaining eximstats in this instance I'm afraid there's not a lot that could be done. optimize eximstats is a script we do have present which will vacuum the database: [root@server cpanel]# /scripts/optimize_eximstats --help NAME scripts::optimize_eximstats SYNOPSIS /usr/local/cpanel/scripts/optimize_eximstats DESCRIPTION This script is used to vacuum (defragment) the eximstats database.
  You might try this to see if there's any change?
