Snappy process the Sentinel-1A Runtimeerror error:17

After processing and writing the product to disk you should call product.dispose(). This should release the memory.
You can also call explicitly the Java Garbage Collector.

Runtime = jpy.get_type(‘java.lang.Runtime’)
Runtime.getRuntime().gc()

But recently there was a general issue found with the S1 reader.

Maybe you have no chance to reduce the allocated memory at the moment.
