I have a number of Python/arcpy applications that use multiprocessing. Not all arcpy commands like to be multiprocessed but some do work. For example, I can create multiple processes that all "append" into  the same SQLServer table from different sources simultaneously.   With ArcGIS Pro v3.3.2 I am finding Python /arcpy applications that multiprocess that used work no longer do. The applications worked with v3.2.3. Is anybody else running into such issues? Test code below to demonstrate issue. I have installed ArcGIS Pro v3.3.2. The results can vary.  - Run as is. The results should produce "<-- did something ..." statement 5 times. This should work. - Uncomment line #2 (from arcpy import Exists). Run app. I start to see issues here in that I no longer get 5 statements. Other errors can appear. - Uncomment line #3 (time.sleep(15)). Run app. Maybe this line helps sometimes\? - Uncomment line #9 (print(Exists("c:\dev\test-upgrade")). Run app. Errors. - Uncomment line #24 (# time.sleep(10)). Run app. In the past, I have used delays to get the new processes to spawn properly. ---------- ---------- ---------- ---------- import time # from arcpy import Exists # time.sleep(15) from multiprocessing import Process import random def do_something(title):    print(" ---> do something", title)    # print(Exists("c:\work\a-file-name"))    time.sleep(random.randint(5, 15))    print(" <--- did something", title) def main():    to_process = [ "Albany", "Boston", "Chicago", "Detroit", "Emporia" ]    procs = []    for item in to_process:       print(" ===> process spawn: ", item)       proc = Process(target = do_something, args = (item, ))       proc.start()       procs.append(proc)       # time.sleep(10)    for proc in procs:       proc.join() if __name__ == '__main__':    main() ---------- ---------- ---------- ---------- ...
