*sigh* Sorry, mozilla mail fails me again.

test.sh
---------------------[start]

#!/bin/sh
while [ true ]
do
        ruby client.rb
done
---------------------[stop]


server.rb
---------------------[start]
#!/usr/bin/env ruby

require 'soap/rpc/standaloneServer'

class SqlCustomerPortServer < SOAP::RPC::StandaloneServer
  class SqlCustomerService
    def self.create
      new
    end

    def deposit(amt)
      "deposit #{amt} OK"
    end

    def withdrawal(amt)
      "withdrawal #{amt} OK"
    end

  end

  Name = 'http://tempuri.org/sqlCustomerPort'
  def initialize(*arg)

    add_rpc_servant(SqlCustomerService.new, Name)
  end

end

if $0 == __FILE__
  svr = SqlCustomerPortServer.new('SqlCustomerPortServer', nil, '0.0.0.0', 7000)
  trap(:INT) do
    svr.shutdown

  status = svr.start

serv.add_method('withdrawal', 'amt')

#serv.wiredump_dev = STDOUT

p serv.deposit(150)

The server and client both work perfectly without memory leaks in 1.8.2 
preview and before. They do not work with stable-snapshot nor the latest 
ruby_1_8 from cvs I just ran 30 minutes ago. The server starts leaking 
when you keep making the client connect over and over. So about after 
800 connections the memory would be exhausted.


These are ready to test scripts, I tool them from NaHi's samples instead 
of using mine. These scripts work fine on 1.8.2 preview.
