 I've been using pipes with file sources and sinks.
 One trick you have to do is start the consumer before the producer. For some reason if the writing on the pipes starts before the reading, things get messed up.
 Try starting the transmitter reading the pipe before you start the process that writes to the pipes. That did the trick for me.

See man 7 fifo on your local Linux system.

Normally, the sending-side will block until the reading-side has opened.

 That's what it should do.

 But in practice, I've seen some blocks locking if their writes were blocked. That's why I suggested starting in this order.
