1.9.3p194 [BUG] Segmentation fault

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 = "/data/cloudable/current/log/process_tweets.log"
logger.formatter =
logger = "../log/process_tweets.log"
logger.formatter =

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! "Processed tweet %d" % tweet.tweet_id
end "Waiting to poll for new tweets"
sleep 5 # wait to poll for new unprocessed tweets
