Body: <p>We run CiviCRM 4.6.2 with Wordpress 4.2.3. I have run a couple of large Mailings recently and they get stuck 'running'.  I know some recipients have received them although the reports say 0% have been delivered.  I don't want to execute the cron job again as previously some recipients then received the mailing twice.</p>
  
  <p>Any ideas?  </p>

  We run CiviCRM 4.6.2 with Wordpress 4.2.3. I have run a couple of large Mailings recently and they get stuck 'running'. I know some recipients have received them although the reports say 0% have been delivered. I don't want to execute the cron job again as previously some recipients then received the mailing twice.
  
  Any ideas?

  As to duplicate sendings you can actually make a group of those that have already received the mailing using "Report" and listing all successful deliveries. You can then use that group to "Not include" when you do your second round.
