Problem :

Loading Cpanel or WHM Link in browser throws this error :

Internal Server Error

more than 400 attempts to create a session failed


cpsrvd/11.25 Server at 1.2.3.4

Reason :
This is most of the time caused by the Inodes hitting their limit inside a VPS.
Resolution:
Check the Inodes usage on the VPS using below command :

df -i


If the usage is indeed 100% then increase the inodes for that vps and then restart it. This will resolve the issue.

      If you are on a VPS try checking and increasing the QUOTAUGIDLIMIT QOS parameter.
      If you are on physical server (which looks like the case from your df -i output) then make sure that /var/cpanel/sessions is a directory and not a file. Secondly if you have a separate /var partition make sure it has free inodes, you can check by doing ‘ df -i /var’
