Multiprocessing in python

Hello,

I am developing a tool to clip raster from a large raster within an arbitrary range from some points.

The number of points is more than 20000, it's enormous.

So, I tried to use multiprocessing in python.

I created a python program.

However, it doesn't work completely.

I tested this python program for 10 points.

Then, 6 out of 10 points were outputted correctly.

On the other hand, 4 points were outputted as empty tables, not rasters.

I guess causes as below ...

(1) Time out of arcpy.Clip_management

(2) Access to one raster from some process

But I can't find any solution.

I attached python file.

If anyone knows of any solution, give me advice or solutions.

Thanks,
