Hello,


I have received the following warning from my cPanel server.
Code:
===================
Disk usage warning
The filesystem “/var/tmp” mounted at “/var/tmp” reached “warn” status because you currently use 84.21% of its available blocks.

Notification Type: warn ⚠
Server: hostname.net
Primary IP Address: xx.xx.xx.xx
Filesystem: /var/tmp
Mount Point: /var/tmp
Percent Used:
84.21%
Disk Block Usage:
Used: 3.12 GB
Available: 636.36 MB
Total: 3.94 GB
ChkServd Version: 17.0


And checking the /tmp directory I can see the folder is filled with session files.

How can I found which process or software is creating this
it's php any site running php will add sess files to your tmp


note: session files are usually very small your examples the largest file is 4k are you sure that they are taking 100% of your space and not something else
