[openib-general] Some CM ib_destroy_cm_id errors?

[Libor Michalek]

Sean,

  
  I'm seeing the following errors in my log file when I try to detroy a
communications identifier. In the first case it is a cm_id which has
never been used, just create, a failed cm_send_req(), and a destroy. The
second case is a listening cm_id which is being destroyed.
