Model builder

Problem: Getting ERROR 999999 while executing function in ArcMap 10.6 model builder.

I want to sum six different variables to a raster and save in a file geodatabase. The six variables are contained in a netcdf (nc4) file. The netcdf files are from the GLDAS-NOAH 3hrly model output. I have about 15 thousand netcdf files (each about 7 MB) for the year 2010-2014 in a folder.

I am using model builder in ArcMap 10.6. The screen shot of the model is attached.

The problem is the model works for about 70-85 files then stops with an error message like the one below:

ERROR 999999: Error executing function.

The table was not found. [VAT_G20000513_1800]

No spatial reference exists.

Failed to execute (Cell Statistics).

[Here, G20000513_1800 is one of the netCDF files that I am processing]

Once I close all program and restart the process, the model runs again stops after processing 70-85 files with a similar error message.

I think the error is memory issue. I installed and tried use background geoprocessing (64 bit) for 10.6. I also saved the intermediate files in a separate folder but it did not help either. Is there a way to resolve this? I am working on Windows 7 Enterprise 64 bit PC with 16 GB RAM

Thanks

do all the tools in your model support 64bit background geoprocessing?

You can check the General tab of the tool properties for the Always run in foreground check box to see if a tool is capable of running in the background.

Yes, they do.

Hi Dan, just a while ago, I re-ran my model in background just to be sure. This time as before, it processed 84 of my netCDF files and stopped with different error message as below:

ERROR 000539: Error running expression: rcexec()
Traceback (most recent call last):
File "<expression>", line 1, in <module>
File "<string>", line 8, in rcexec
RuntimeError: ERROR 999998: Unexpected Error.

The table was not found. [VAT_rastercalc1]
Failed to execute (Raster Calculator).

bad netcdf perhaps... something didn't work, so shift your inputs and see if it stops at a different number (ie skip the first 10 in your list and see if it only processes 74... if it does, then that is the bad one).

Thank you Dan.  I have tried option you suggested. I am pretty sure that the issue is not with netcdf data. Once the model stops with an error and I restart from the point where it stopped before, it runs again for about 70-85 files.

sounds like resources then... Pro and a beefier machine if judicious in-model cleanup isn't possible... may be time to export the model to a script too, you might have better control over deleting/removing unneeded objects during the processing.

You should probably put preconditions on your Delete calls to make sure the Copy Raster happens before you delete the layer that reads it.
