Hello,

We have some hosting servers running latest cPanel (11.48.3) and Litespeed (4.2.3) with Cloudlinux/CageFS enabled.
On one server some customers get 503 occasionally on their sites.

When I check logs I get these:

When checking stderr.log I see these:

Any idea what is causing these?
I may think the errors in stderr may be related to 503 errors somehow?

Are you using PHP Selector as well? We've had these issues too. Sometimes disabling some modules in PHP selector like zend guard loader helps.

Ok. Yes, we use PHP Selector.
Do you mean disable them on whole server or just the one account that has problems?

We cannot disable those modules for the whole server.....
