"Sorry for the inconvience!
The root partition on this server is running out of disk space. Cpanel operation has been temporarily suspended to prevent something bad from happening. Please ask your system admin to remove any files not in use on that partition."
What is the files that I should delete in the partition?I have checked on the WHM , the Disk sda5 (/) is using 94% usage and Disk sda2 (/usr) is 86 % usage.
