Hello @sophiajhondeveloper
Which server os is this ? e.g. Ubuntu 20.04
Which php version are you using for this website ? e.g. php 7.4
Are you using latest version of cyberpanel ?
Ubuntu : Is at latest 20.something
PHP: 8.0
Cyber panel Version :
Current Version: 2.3
Build: 3
Current Commit: eb9eafd4daef7b244fb590c830e3fb3a8d5818f6
This is a php process issue
It usually happens with some PHP script takes long time to finish, or have a bug causing an infinity loop. People keep refreshing that URL, all PHP worker processes are occupied by the long run script, cannot take new request any more. For some cases, increase the timeout or number of worker processes can help. The eventual fix is to fix the script. Usually it is not some thing can be taken care of automatically by web server.
Can you try this
# deletes php 8.0 session folders and recreates them
$ killall lsphp
$ rm -rf /var/lib/lsphp/session/lsphp80; mkdir -p /var/lib/lsphp/session/lsphp80; chmod 1733 /var/lib/lsphp/session/lsphp80
Then increase Max Connections to the maximum number of concurrent LSPHP processes you want to allow by:
- Go to WebAdmin Console https://SERVER_URL:7080/
- Server Configuration > External App > LiteSpeed SAPI App
- Click Edit
- Increase Max Connections to the maximum number of concurrent LSPHP processes you want to allow.
- Set Environment to
PHP_LSAPI_CHILDREN=the maximum number of concurrent LSPHP processes you want to allow.
- Apply Changes and click on Graceful Restart or run in terminal
service lsws restart

Do you have any idea how much bit port of server is needed if you traffic of 15000-25000 per day ? and which server is best for it?
That depends with the provider. You should contact your provider’s support to better understand how they charge you vs what they offer
Throttling is different for all providers there is no general answer for this.
Has your issue been resolved so far ?
