Can you describe the sequence how you are invoking rt_pipe_open()/open()/rt_pipe_delete()?
If the following description applies to you then you discovered what we've discovered
before and there is no easy fix for that as far as I know.
1) create pipe with rt_pipe_open()
2) connect to it by opening /dev/rtp7 with open()
3) delete pipe with rt_pipe_delete() (for example by killing the Xenomai application)
4) create same pipe again with rt_pipe_open() (for example by restarting the
Xenomai application with /dev/rtp7 is still open)
--> rt_pipe_open() reports an error
