title: Problem in migrating to LAMP from XAMPP.. Memory limit error
body: <p>I was using XAMPP for my local machine but as I wanted to run applications like mysql work bench and some test frameworks I decided to switch to LAMP self install. I'm using ubuntu and followed the instructions at: <a href="https://help.ubuntu.com/community/ApacheMySQLPHP" rel="nofollow noreferrer">https://help.ubuntu.com/community/ApacheMySQLPHP</a></p>
  
  <p>But the problem is LAMP is consuming too much of my memory (RAM) I've allocated 124 MB currently but still it gives me memory exhausted error when I run Drush (Drupal command line). When I do drush cc to clear cache it give me the following:</p>
  
  <pre><code>    Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 122880 bytes) in /var/www/----/sites/all/modules/ubercart/uc_order/uc_order.order_pane.inc on line 150

  <p>In each error it shows me a back trace and I guess this default debugger I'm not aware of in Apache or my PHP config it eating up the memory. If anyone can help I"d be glad.</p>
  
  <p>Another error below:</p>
  
  <pre><code>    Fatal error: Call to undefined function dsm() in /var/www/-----/sites/all/modules/custom/gtpath/gtpath.module on line 180
