My Apache is freezing at least once a day with error message:

[Tue Oct 07 05:29:52 2014] [error] server reached MaxClients setting, consider raising the MaxClients setting

Don't select 'optimize' in 'apache optimize'. Since certain version of v7, MaxClients set max as '400' (no more).

I had the same issue: http://forum.mratwork.com/kloxo-mr-development/apache-hang-ups/

I raised the open files to 4096 and ever since i haven't had the issue.
