Occasionally, in my Apache error log, I will find:
[error] server reached MaxClients setting, consider raising the MaxClients setting
I've purposely lowered MaxClients in the past (to 60) due to issues with running out of memory, but I'd like to know exactly what's happening on the user's end when this limit is reached on the server. Does the page they're accessing just take longer to load? Do they get some sort of error message?
