Excessive resource usage: apache

Hi,

Seeing very high volumes of files in /root/Maildir/new saying:

Subject: lfd on server: Excessive resource usage: apache (47245 (Parent PID:33410))
Message-Id: 20170508132306.7B76E2A2000@server
Date: Mon, 8 May 2017 14:23:06 +0100 (BST)

Time: Mon May 8 14:23:06 2017 +0100
Account: apache
Resource: Virtual Memory Size
Exceeded: 438 > 200 (MB)
Executable: /usr/sbin/httpd
Command Line: /usr/sbin/httpd
PID: 47245 (Parent PID:33410)
Killed: No

Can anyone advise what is causing this/how do I fix?

First check what is your memory consumption and what is your total memory. Then proceed to check Apache settings. It could be your server have low memory, bad script or bots probing your website. Either way you should post little more information.
