Ruby-net/ldap模块内存泄漏

这个问题似乎在某种程度上与LDAP库有关,因为当我删除对LDAP的调用时,内存使用情况稳定得很好。此外,正在扩散的物体是 Net::BER::BerIdentifiedString 和 Net::BER::BerIdentifiedArray ,都是LDAP库的一部分。

以下是我的代码的相关部分:

require 'net/ldap'
require 'pp'

class User < ActiveRecord::Base
  validates_presence_of :name, :login, :email

  # This method is resonsible for populating the User table with the
  # login, name, and email of anybody who might be using the system.
  def self.import_all
    # initialization stuff. set bind_dn, bind_pass, ldap_host, base_dn and filter

    ldap = Net::LDAP.new
    ldap.host = ldap_host
    ldap.auth bind_dn, bind_pass
    ldap.bind

    begin
      # Build the list
      records = records_updated = new_records = 0
      ldap.search(:base => base_dn, :filter => filter ) do |entry|
        name = entry.givenName.to_s.strip + " " + entry.sn.to_s.strip
        login = entry.name.to_s.strip
        email = login + "@txstate.edu"
        user = User.find_or_initialize_by_login :name => name, :login => login, :email => email
        if user.name != name
          user.name = name
          user.save
          logger.info( "Updated: " + email )
          records_updated = records_updated + 1
        elsif user.new_record?
          user.save
          new_records = new_records + 1
        else
          # update timestamp so that we can delete old records later
          user.touch
        end
        records = records + 1
      end

      # delete records that haven't been updated for 7 days
      records_deleted = User.destroy_all( ["updated_at < ?", Date.today - 7 ] ).size

      logger.info( "LDAP Import Complete: " + Time.now.to_s )
      logger.info( "Total Records Processed: " + records.to_s )
      logger.info( "New Records: " + new_records.to_s )
      logger.info( "Updated Records: " + records_updated.to_s ) 
      logger.info( "Deleted Records: " + records_deleted.to_s )

    end

  end
end

提前感谢您的帮助/指点!

顺便说一句,我在net/ldap支持论坛上也问过这个问题,但是没有得到任何有用的提示。
