Subject: SystemStackError: stack level too deep

Now I am writing a server code to handle each connection by forking a
new process. Here is the code:

@tcpServer = TCPServer.new(host, port)

while true
  if tcp = @tcpServer.accept
    fork do
      // handle all request in this connection
    end
    tcp && tcp.close
  end
end

@tcpServer.close_read
@tcpServer.close_write

I also set up trap to handle CLD signal:
  trap("CLD") {
        pid_info_array = Process.waitall
      }

After a period of time, I got the error:

SystemStackError: stack level too deep

The position is at the line of Process.waitall.

I have tried to use Process.wait, but this problem still exist.

Any ideas. Thanks.
