title: Xdebug with PhpStorm won't stop at random breakpoints
body: <p>I recently installed Xdebug on my server and I have a very strange problem : </p>
  
  <p>Sometimes, Xdebug don't stop a breakpoint, sometimes it does. It is very confusing because I spent time investigating why PHP didn't go to a certain point of my code, before understanding that it was only Xdebug that "choose" randomly which breakpoint it want to stop, and which it doesn't want. I tried to close PhpStorm and restart it, and <strong>sometimes</strong> some of the breakpoints work again and other doesn't anymore. It seems that its completely random.</p>
  
  <p>I'm using PhpStorm 2019.1, and Xdebug 2.7. I did the PhpStorm Xdebug validator that told me everything is OK with the Xdebug config. </p>
  
  <p>I'm using Xdebug with "zero-configuration", calling scripts from Chrome with the extension. Do you think it can be a bug of PhpStorm?</p>
