Bug #1557: Memory leak in DRb
http://redmine.ruby-lang.org/issues/show/1557

Hi,
I just made a stress test on my distributed ruby service, and I think there is a memory leak, at least in Windows version. It seems that the memory used by the server grows as the clients keep using remote methods. I used the following code samples and created a lot of clients connecting the service.

Service code:

require 'drb'
class Ser
  def getAnswer
    42
  end
end
DRb.start_service("druby://:12345",Ser.new)
DRb.thread.join

Client code:

require 'drb'
DRb.start_service
service = DRbObject.new(nil, 'druby://carotte:12345')
while true
  s = service.getAnswer
  pp s if ! ARGV.empty?
end
