Campaign email "stuck" at 47%

I have a simple campaign email setup. The segment list is 875 contacts. I triggered the campaign manually by calling the cron job from my web browser. Several emails are sent - but not all of them. When I open the “Actions” tab of the campaign it shows 47% “send email.” Does that mean that only 47% of the emails were sent? The “Sent email status” pie chart totals to 400 (330 ignored, 70 read).



I have rerun the cron job several times. Here are the results.

Code:
Triggering events for campaign 31 Triggering first level events 468 total events(s) to be processed in batches of 100 0/468 [>---------------------------] 0% 46/468 [==>-------------------------] 9% 92/468 [=====>----------------------] 19% 138/468 [========>-------------------] 29% 184/468 [===========>----------------] 39% 230/468 [=============>--------------] 49% 276/468 [================>-----------] 58% 322/468 [===================>--------] 68% 368/468 [======================>-----] 78% 414/468 [========================>---] 88% 460/468 [===========================>] 98% 468/468 [============================] 100% 0 event(s) executed

I'm stuck on what to check. I am using Amazon SES to send the emails.
