python multiprocessing daemon
It is not possible to have 100% confidence in an answer without knowing what is going on in the child/daemon process, but consider if this could be it. Since you have worker threads in your child process, you actually need to build in some logic to join , According to multiprocess daemon documentation by setting d.daemon=True when your script ends its job will kill all subprocess. That occurs before they can start to write so no output will be produced.,When you see [INFO/MainProcess] calling join() for process p1. it means the main process has not exited yet -- it's in the process of shutting down, but of course will not be done shutting down until that join returns... which will happen only once th,multiprocessing is a package that supports spawning processes using an API similar to the threading module. The multiprocessing package offers both local and remote concurrency, effectively side-stepping the Global Interpreter Lock by using subprocesses i,17.2.2.1.
