Some websites are not working on Litespeed

[Sajawal]

Hi,

I am facing issues on some of my websites, which are not working and display 503 error and I don't know when exactly this issue occurs. There is no space and inode issue.

The logs of one website are mentioned below.

Please let me know what can be issue.

You mentioned there is no space and inode issue, do you mean that your server hard disk is full?
This will affect the writing of temporary files to /tmp directory and result in an error.

No harddisk is not full, there is plenty of space left on my server.

 

[kodeslogic]

Do you see any error in the web server error_log file when you visit the website?

 / usr / local / apache / logs / error_log

This error can happen on reaching PHP memory_limit on the server. This PHP internal memory limit is normally managed by the php.ini file.

Do you have any cache modules for the concerned website?
Have you tried checking by disabling the CSF?

There isn't any cache module running and I have also disabled the CSF too but the same error.

 

[kodeslogic]

In that case, I would suggest opening a support ticket to the cPanel team or getting in touch with Certified System Administrators to investigate this further.

You could also disable Litespeed and see if the error changes in any way. But yes, with the troubleshooting you've done it sounds like it might be time to open a ticket.
