title: Heroku - How to avoid memory_limit issue in cron scheduler
body: <p>We have two dynos</p>
  
  <p>One running for web and another for scheduler.</p>
  
  <pre><code> web: vendor/bin/heroku-php-apache2 -F fpm_custom.conf public/
   sheduler: php artisan schedule:daemon 
  </code></pre>
  
  <p>There are 4 different cron tasks and all working fine.
  But one of them is heavy weight and it need higher memory_limit.</p>
  
  <p>But not sure how can we increase the memory_limit against that scheduler dyno only ?
  The same issue was there in web too but can able to override the issue with fpm_custom.conf.</p>
  
  <p>I tried below method in Procfile</p>
  
  <pre><code>sheduler: php -d memory_limit=1024M artisan schedule:daemon 
  </code></pre>
  
  <p>But seems to not helped.
  So any help how we can override the issue ?</p>
