What is the difference between the two configurations (besides
identical MPM parameters)? Things like EnableMMAP and EnableSendfile
matter too for instance.

Do the two systems have the same `ulimit -n` (or LimitNOFILE in
systemd) for httpd?

Also, do you see errors in the error_log file? Maybe "LogLevel
mpm_event:trace1" could help see what happens while not being too
verbose.


Regards;
Yann.
