[issue32759] multiprocessing.Array do not release shared memory

2018-02-03 Thread OO O 

OO O <dogod...@gmail.com> added the comment:

mp.heap.BufferWrapper._heap = mp.heap.Heap ()
gc.collect ()

This is working!! The memory is cleared.
Just delete the globe _heap and recreate a new one, but is the the correct 
way???

[issue32759] multiprocessing.Array do not release shared memory

2018-02-03 Thread OO O 

New submission from OO O <dogod...@gmail.com>:

OS: Win10 / 8.1
Python: 3.5 / 3.6

My program use mp.Array to share huge data.
But suffer from out of memory after running for a while. 

But Windows task manager didn't show which process use that huge memory. And I 
use pympler to check my python memory usage. Still shows noting. So, I use 
RamMap to check, it shows a huge shared memory is used.

I can reproduce the case by the simple test code:
   #---
   import numpy as np
   import multiprocessing as mp
   import gc

   def F ():
   a = mp.Array ( 'I', 18, lock = False )

   #
   F ()
   gc.collect ()
   #---

No matter how hard I tried. the memory is not released.
I put what I tried in the attachment picture.
