Is it LiteSpeed spamming error.log in lsws/logs or large tmp files?
Using CyberPanel for managing your server, you might come across with full disk space problem. You notice that there is suddenly a huge increase in disk usage on your CyberPanel dashboard. Some times you will get the following error
503 Service Unavailable – The server is temporarily busy, try again later!
Lets identify what may have caused this huge increase in disk usage and how can you prevent this from happening again?
If you are using CyberPanel, look for the following directories as they must be containing large files that you won’t need.
But if the logs are growing continually, Spamming error.log in lsws/logs, removing them manually is not very practical. You Have to find out what is causing error by checking the error.log files and try to fix the error.
You can delete log files in a cron job. Login as root via SSH. Open crontab

/home/domain.com/backup
