    Monit is a daemon monitoring tool that will restart failed daemons.
    It looks like monit was trying to start something that failed.

    Apache logs keeps showing this

    server reached MaxClients setting, consider raising the MaxClients setting

    I had it on 200, changed it to 250 and it still shows this, even 5 minutes after reboot.

    Why?

    Is your server very busy? Run this to see how many unique addresses
    are actually connected to you.

    netstat -ntu | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | wc -l
