@wanghaEMQ this is related to #325 and #2193

Unfortunately, this is not trivial to fix with the current design. If you gracefully shut down your applications, you should not encounter this issue. From the log it looks like the applications did not have the chance to cleanup its resources and where killed in the middle of a transmission.

This issue will finally be fixed by iceoryx2 which should be on feature parity with iceoryx later this year and also have C and C++ language bindings.

Ok. Thanks. I will shutdown gracefully and try.
