Suea-php74.sock Connection refused!

#1
Hello everyone, I installed litespeed with a trial version on approximately 10 servers in the last week. within 6-7 days after installation

Websites become inaccessible with an error similar to the one below (503 error). The error details are not exactly the same on all servers, but there is definitely data about this file in the error logs. "uds://usr/local/lsws/extapp-sock/APVH_user_Suea-php74.sock"

I solve this problem by deleting the relevant PHP version and reinstalling it. But I want to avoid this completely.
1- What is the reason for this error?
2- What should I do to prevent it from happening again?
