SSL connection timeout and Apache restart issue
« on: October 05, 2021, 05:16:24 AM »
Hello,

We are frequently facing the apache restart issue on the server and getting following error logs:

1. These are just warnings.
2. Try to change MPM to Prefork ;)
You can ask me to solve any problem with your server for some money in pm  ;)

We are using the Apache Event Worker on our server, so it's safe to change the Worker from Event to Prefork.

```
[root@server apache]# /usr/local/apache/bin/apachectl -M | grep mpm
 mpm_event_module (static)
```
