ServerLimit and ThreadLimit configure the size of an internal structure which maintains data about processes and threads. This structure is only created during Apache start, so if you want to change these two params, you need to stop and start.
ThreadsPerChild and MaxClients can be changed and activates with "apachectl graceful", no need to restart. Only if ThreadsPerChild needs to get increased higher than ThreadLimit, or MaxClients/ThreadsPerChild needs to be increased higher than ServerLimit, you need to adjust these as well and therefore need a completely new start.
So if you want to reserve some reserve space for ThreadsPerChild or MaxClients, you should configure ThreadLimit = ThreadsPerChild + "reserved additional threads" and ServerLimit = MaxClients/ThreadsPerChild + "reserved additional clients"/ThreadsPerChild.

Thanks,
I should have mentioned that I'm running Apache HTTPD 2.2 on a RHEL6.7
system. There it is tied to MaxClients which is getting changed at
restart. I believe, according to this that I need to do a full stop and
start to get this to work.
Thanks for your help!

Reading the doc, seems that ServerLimit is related to
MaxRequestWorkers (which has a default set to 256).

Hello,
While reloading httpd did increase MaxClients to 400 as
specified, it did not increase ServerLimit to 400 as
specified. What is worse is that since ServerLimit remained
at 256, this caused MaxClients to be reduced to 256 since
ServerLimit seems to be the hard limit for MaxClients.
Even more frustrating is that when I did a service httpd
restart, it not only did not increase ServerLimit to 400, but
it threw an error that the attempt to increase ServerLimit
during a restart was ignored.
Any ideas why I cannot increase the ServerLimit?
Thanks,
Laurence Cohen

Hi,
I need to increase my httpd server's MaxClients and
ServerLimit. Can I just do a
service httpd reload
to load the new settings?
Or do I need to do a
service httpd restart
to load the new settings?
This is on a production server with active users, so
obviously the former is preferable.
Thanks,
Larry Cohen
