/var directory too full

[Doctor]

All my servers have a standard 3.9GB space allocated for /var directory. None of them use more than 30% of the allocated space except for one server with over 80% space occupied. Server is running RedHat 7.3 with WHM 8.5.4 cPanel 8.5.4-R72.

I have already listed out the space usage for all files on that directory but couldn't find any abnormalities. All the files are exactly the same as my other servers' /var directory ... and yet it occupies over 80% of 3.9GB. Why? How can I free more space for the /var directory on this particular server?

look to see if you have apache core dumps in there. That happened to me one time.

[Doctor]

What should I do if there is?

it is safe to delete apache core dump files. That is fron where apache freeked out and did a memory dump but you might want to double check.
