I got this email today:
IMPORTANT: Do not ignore this email.
Apache has reached the MaxClients
limit. cPanel has increased the MaxClients limit to 170 (10 higher).

What would be the best thing to do:
1) manually increase MaxClients to a higher value, but risk a system crash.
OR
2)Let cPanel update it when needed. This causes apache restart every time it increases the MaxClients value.

What's your opinion?

Thanks,

set it to 256 and restart apache

Hi ,

i think you have changed the time out of your httpd.conf settings,
the default is 300 sec . the longer u set it the longer a session is maintained and along with it if the number of users accessing the site increases..Hence , you get that messsage

Correct me if i m wrong some one !!

Cheers :)

dbbrock1,
Check your logs. You will probably see the result of 'mini' dos attack (for lack of a better description). Looking over the forums at Cpanel, I see that this has become frequent lately. In my logs I will see hundreds of entries from somebody hitting our servers in a matter of seconds. It doesn't last long, but it will cause the max connections issue.

Yep agree with Tom it happens all the time on my servers.

I dont' get the max connections error, but I've had apache crash a couple of times with things like that in the logs.
