title: mpm_prefork:error AH00161: server reached MaxRequestWorkers setting
body: <p>I have a simple magento website on a small AWS Ubuntu server and a small RDS, with only me visiting it. Every 3-5 minutes, apache crashes with this error:</p>
  
  <p><code>[mpm_prefork:error] [pid 7390] AH00161:server reached MaxRequestWorkers setting</code></p>
  
  <p>Right when it crashes, I have about 900M free memory of 2G. I checked the access logs and there are no other IP addresses but me. In the mpm_prefork.conf file, the default value for MaxRequestWorkers was 0; changed it to 150 and that has had no effect. </p>
  
  <p>I have set up over a dozen Magento websites on AWS instances, and even more wordpress websites and I have never run into this issue. Does anyone have any good ideas why apache2 would do this right out of the box? This AWS instance is only a few days old.  </p>
  
  <p>Ubuntu 14.04.3 LTS
  Apache/2.4.7
  PHP 5.5.9-1ubuntu4.17</p>
  
  <p>UPDATE: I've started a new t2.small EC2 instance, with only me visiting (confirmed in access.log) and copied the website over. It still points to the same RDS that hasn't changed. I'm getting the exact same error still! Any ideas?</p>
