In OpenShift 4.12, the default httpd container "net.core.somaxconn" value is only 128

Solution Verified - Updated -

Issue

The current sysctl net.core.somaxconn setting is only 128, which might impact the user-workload. This setting limits how many half-open connections can wait to be accepted, affecting how the incoming traffic is managed.
