communication between 2 processes

A multithread process (thread 1) sends a Message to another process
(process 2).
The problem: the Send-function doesn’t return back and hangs up.
What could be the problem?

This question is described very generally. Yet I still don’t have that
much experience in developing QNX applications with photon.

I hope anybody can give me a helpful advice.

Thank you.
Tobias.

Process 2 doesn’t reply ?
