You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: problem_recacher.rb
    path of file: ./repos/errbit/app/interactors
    
    the code of the file until where you have to start completion: class ProblemRe
    
  def self.run
    count = Problem.count
    puts format(LOG_START, count)

    Problem.no_timeout.each_with_index do |problem, index|
      problem.recache
      problem.destroy if problem.notices_count == 0

      next unless (index + 1) % LOG_EVERY == 0
      puts format(LOG_ITR, (index * 100 / count), count - index)
    end

    puts "Finished re-caching problem attributes"
  end
