Here’s a few fixes you can try:
Fix #1: Clear up unnecessary logs in
/usr/local/cpanel/logs/
/usr/local/apache/logs/
/usr/local/apache/domlogs/
Fix #2: Remove unnecessary old or duplicate folders such as
/usr/local/apache.*
/usr/local/maldet.*
Fix #3: CAUTION: This should only be done as an absolute last resort. This fix is dangerous and if done incorrectly can break your server. You should only do this if you are an experienced system admin. If not, ask someone experienced to do this for you. This method is not recommended by cpanel. This is just a workaround to resolving this where there are no other options rather than reloading your entire server
1) Stop crond, exim, cpanel, apache, mysql, leechprotect
2) Verify none are running by typing: lsof | grep /usr/local/cpanel
3) Make an empty folder at: /home/usr/local
4) Move /usr/local/cpanel to /home/usr/local/cpanel
5) Make an empty folder at: /usr/local/cpanel
6) Set the permissions: chmod 711 /usr/local/cpanel
7) Add the following line to the /etc/fstab file (save a copy of the file first before editing it):
/home/usr/local/cpanel /usr/local/cpanel none rw,bind 0 0
8) Mount the folder: mount /usr/local/cpanel
9) Now restart all of the services that were stopped
10) Update cpanel: /scripts/upcp –force
