Logging form delayed job class

I have asked this before without any luck, trying again.

this is what I have in my dj.rb initializer

Delayed::Worker.backend = :active_record
Delayed::Worker.logger = Rails.logger
#Delayed::Worker.logger = ActiveSupport::BufferedLogger.new("log/
##{Rails.env}_delayed_jobs.log", Rails.logger.level)
class Delayed::Job
    def logger
        Delayed::Worker.logger
    end
end
if JobsCommon::check_job_exists("PeriodicJob").blank?
    Delayed::Job.enqueue PeriodicJob.new(), 0,
Constants::PROCESS_FREQ.from_now
end
#end

This is my job class

class PeriodicJob
    def perform
        this.logger.info "Periodic job writing #{Time.now}"
# Rails.logger.info "Periodic job writing #{Time.now}"
        if JobsCommon::check_job_exists("PeriodicJob").blank?
            Delayed::Job.enqueue PeriodicJob.new(), 0,
Constants::VOTE_PROCESS_FREQ.from_now
        end
    end
end

the job fails with the error message

2010-08-09T13:29:59-0700: [Worker(delayed_job host:ubuntu pid:8941)]
acquired lock on PeriodicJob
2010-08-09T13:29:59-0700: [Worker(delayed_job host:ubuntu pid:8941)]

I am sure this has been done before.

Please help.
