Batch Processing complete in 6 hours: OutOfMemoryError


I’m trying to process a batch of 20+ Sentinel-1 scenes using a single graph in the SNAP GUI.

1 of the scenes processes fully and then I get an out of memory error:
“java.lang.OutOfMemoryError: Java heap space”

I have 20G memory allocated in the config.

Do you have any suggestions?

Actually I think the error occurs during the processing of a single scene. Maybe 20G is not enough RAM for Sentinel-1 polarimetry?
