When trying to do some of his operations, the function can find that 
internal data of the queue is not correct (number of processes waiting, 
the value of internal pointers, etc...). Or when the object you are 
trying to pass is not really a shared message queue (an error that some 
  POSIX functions return when the descriptor you are using is not really 
what you thought it was (or it was closed).

Hope this helps,
