That message is the result of some other problem and not the cause of the problem itself. To analyze the real problem you'll have to post the other error messages as well. The message is just an informative one. Try doing a "reset" of the job and looking at the log entry starting with "...from previous run..."
Your job blew up. Seriously, that's all that means. As noted, there should be other supporting messages logged as to the cause, that or you need to Reset the job and look for a 'From previous run...' log message.
