I am trying to process tweets on engineyard for a rails app and constantly get segmentation faults, seemingly at random. The core and trace are below:


  require '../config/environment'

  Process.daemon true, false #daemonize me

  if Rails.env == "production"
    logger = Logger.new "/data/cloudable/current/log/process_tweets.log"
    logger.formatter = Logger::Formatter.new
  else
    logger = Logger.new "../log/process_tweets.log"
    logger.formatter = Logger::Formatter.new
  end

  while true

    tweets = Tweet.where(:processed => false)

    tweets.each do |tweet|
      user = User.where(:twitter_uid => "#{tweet.user_id}").first # should be unique

      if user
        h = {:text => tweet.text, :id => tweet.tweet_id, :created_at => tweet.created_at,
             :url => tweet.urls.first}

        tweet.processed = true if TwitterJob.find_or_create user, h
        tweet.save!

        logger.info "Processed tweet %d" % tweet.tweet_id
      end
    end

    logger.info "Waiting to poll for new tweets"
    sleep 5 # wait to poll for new unprocessed tweets

  end
