Title Photon server's priority
Ref. No. QNX.000009866
Category(ies) Development, Configuration
Issue Photon server's priority value is 10 (default). When our application runs, the Photon server's priority priority is up to 29 (temporary).
Is this normal and what is the explanation?

Solution Photon priority floats, so it will be 29 when a client running at 29 priority is being serviced. The 29 is the default priority of the termination thread, and what your customer is seeing is  Photon cleaning up after an application's termination.
