I would look at /etc/security/limits.conf and /etc/security/limits.d and see if there is a special memory entry for the user httpd is running as. If there is you could change it but this just moves the point of failure. Have you opened a ticket with Red Hat? They may be able to find a the fix from a newer version of Apache and backport it.
As to how Apache 2.4 handles reloads it gracefully stops the existing instances and spawns new ones I have not done an exhaustive test of your problem but I handle about 200 virtual hosts on the central web server here at the University. I do reloads often and have not had the issue with Apache 2.4.

Using a demo host with 260 vhosts, the httpd hangs after "only" 1000 reloads. The relationship seems to be the following: number of virtualhosts = x/number of reloads 10 virtualhosts = 100000 reloads 100 virtualhosts = 1000 reloads Tomorrow I 'll try to test httpd 2.4.x. Other better ideas?

Now I'm trying the php loop against another web server. Then I will try with apache 2.4.x in a offline env. My question is the same: After xx reloads under yy load average in zz time the error will appears "every time". Any smarter suggestion?
