title: Let two Containers getting linked to eachother
body: <p>I have a couple of docker Containers and one special case that two of them have to talk to each other, so they must know each other at best via link.
  I can link one Container to the other but the problem is, that i can't tell them that the second one can talk back to the first.</p>
  
  <p>I tried to create and run the first container and stopped it, then i created started the second container and stopped it as well. Next up i started the first container again with the link to the second and started the second one linked to the first.
  After this my machine went crazy the docker process took all CPU and Memory and neither of the containers was accessible. When you killed the process a new one poped with the same.
  Even when i deinstalled docker restarted the machine and installed docker again it get back to to the crazy state without even starting one of the containers.</p>
  
  <p>Got anyone a solution how to link two containers to each other or let them talk to each other in both directions? </p>
