[Bug 66345] New: Apache2 not working properly when mod_ssl is loaded

https://bz.apache.org/bugzilla/show_bug.cgi?id=66345

            Bug ID: 66345
           Summary: Apache2 not working properly when mod_ssl is loaded
           Product: Apache httpd-2
           Version: 2.4.54
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: blocker
          Priority: P2
         Component: mod_ssl
          Assignee: bugs@httpd.apache.org
          Reporter: ngvhoang@gmail.com
  Target Milestone: ---

This is the setup that we use:
- Apache2 (version 2.5.54) on Ubuntu 20.04.5, OpenSSL 1.1.1q with mod_ssl
enabled
- Backend is a cluster of 2 JBOSS-EAP 7.0 nodes

The connection between Apache2 and JBOSS is ssl-enabled with selfsigned
certificate.
What we notice is:
- when we just load the module mod_ssl.so (without any configuration of SSL
directive), we see that the request from browser to Jboss Web application will
failed (it is retried by Apache2 which breaks the business processing in web
app) if the request takes more than about 17 seconds.

Do you have any idea why this happens?

--- Comment #1 from ngvhoang@gmail.com ---
when apache2 service is running, I noticed these 2 error logs from time to
time. I don't know if they are related to the issue:
