This may cause any other process to get an exception when it tries to use the queue later on. Warning If a process is killed using Process.terminate() or os.kill() while it is trying to use a Queue, then the data in the queue is likely to become corrupted. The multiprocessing pool implementation does spawn a new worker process and 99.99% of the time everything works well.Ġ.01% of the time there are some strange issues and the whole pool stops working, which I believe is because of this issue which is documented in the python docs: I implemented that in a rather ugly way, when the timeout is reached I os.kill the process.
#Nox stuck at 99 system init timeout code
Python's multiprocessing pool has various limitations, one I tried to solve with my wrapper code is the timeout of worker processes. Is there a way of logging how far through all the processes I am with pebble? Corrupted Queue in Python's multiprocessing Pool implementation In python multiprocessing Manager().Queue() has the function qsize() which returns the number of processes completed or running. Feature Request: Number of processes completed for logging. I have a Ubuntu 18.04.1 LTS machine completely up to date that does not have the same issue. I suspect maybe something is happening too quickly before all the processes are closed.

You can see the commented time.sleep(2) at the end.
