MySql Memory Error

I am getting the following error when I try the following code.

controller.rb

  def index     @stats = SubscriptionPayment.stats if params[:page].blank?     @subscriptions = Subscription.paginate(:include => :account, :page => params[:page], :per_page => 30, :order => 'accounts.name')   end

index.html.erb

<% @page_title = 'Subscriptions' %> <% if @stats %>   <h1>Revenue Summary</h1>   <table id="stats">     <tr>       <th>Last Month</th>       <td><%= number_to_currency(@stats[:last_month]) %></td>     </tr>     <tr>       <th>Last 30 Days</th>       <td><%= number_to_currency(@stats[:last_30]) %></td>     </tr>     <tr>       <th>This Month</th>       <td><%= number_to_currency(@stats[:this_month]) %></td>     </tr>   </table> <% end %>

<h1><%= @page_title %></h1> <table id="subscriptions">   <tr>     <th>Account</th>     <th>Amount</th>     <th>Created</th>     <th>Next Renewal</th>     <th>Status</th>   </tr>   <% @subscriptions.each do |subscription| %>     <tr class="<%= 'expired' unless subscription.current? %>">       <td><%= link_to(h(subscription.account.name), [:admin, subscription]) %></td>       <td><%= number_to_currency(subscription.amount) %> <%= "(# {subscription.discount.name})" if subscription.discount %></td>       <td><%= subscription.created_at.strftime("%d %B %Y") %></td>       <td><%= subscription.next_renewal_at.strftime("%d %B %Y") %></

      <td><%= subscription.state %></td>     </tr>   <% end %> </table>

<%= will_paginate(@subscriptions) %>

ERROR

ActiveRecord::StatementInvalid (Mysql::Error: Out of memory (Needed 2096048 bytes):

How do I get around this or fix the current statements?

Thank you,
