Spatial Analyst CreateRandomRaster issue

Question

Hi everybody.

I have a strange issue here when running arcpy.sa.CreateRandomRaster depending on the size of the extent.

I'm running ArcGIS Desktop 10.6 with 64bit geoprocessing in Windows 10

if I run this code in the python window:

ext1 = arcpy.Extent(4054000,2329000,4260000,2597000)

ras1 = arcpy.sa.CreateRandomRaster(1, 100, ext1)

everything works as expected and I get my raster

but....

when I run:

ext2 = arcpy.Extent(4743000,4518000,5240000,5309000)

ras2 = arcpy.sa.CreateRandomRaster(1, 100, ext2)

I get a popup window saying that the background processing has encountered a serious error.

Obviously I get the same issue running the tool from the sa toolbox even in foreground processing mode.

A colleague here with ArcGIS 10.5.1 with 64bit geoprocessing in Windows 10 does not absolutely have this issue.

Any idea ?

Then you lack memory to complete the task

but....if I make it a bit smaller...(maxx= 5000000, maxy=4750000)

it works !!

Not for me...

Very strange. Two computers with 10.6 are behaving this way the others with 10.5.1 are ok.

It must depend on some local settings.

I'll try to investigate the message.

Thanks Dan
