As a consequence, HTTP/2 connections timed out and httpd became unresponsive. This bug has been fixed, and HTTP/2 connections now work as expected in the described scenario. (BZ#1518737)</li> Enhancement(s):<br><li> This update adds the modmd module to the httpd24 Software Collection. This module enables managing domains across virtual hosts and certificate provisioning using the Automatic Certificate Management Environment (ACME) protocol. The modmd module is available only for Red Hat Enterprise Linux 7.
