The /usr partition on this server is running out of disk space. WHM 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.

You can check the size of error_logs and access_logs on your Linux server and in case these files are large you can empty them by using following commands –

#cd /usr/local/apache/logs
#ls -sh error_logs
#ls -sh access_logs 

The log files will generally be in the size of GB’s

#echo > error_logs
#echo > access_logs 

This should resolve the issue.
