How to clear cache in esa_snappy Snap 10.0

I think you will find my answer to this post helpful.

Why SNAP doesn't clear memory after closing the products?

Java manages the allocated memory. SNAP can only mark the memory as not used anymore. Which it does (in most cases). You can enable a little performance widget in SNAP. Click on the toolbar and select Performance. You will now see a memory graph, showing the used and the allocated memory values. [image] Clicking on the graph tells Java/SNAP to free used memory immediately. The first number, the used memory, will get smaller but the second, the allocated memory, stays almost the same. Window…

You can try to call the garbage collection directly.
See here:

How to free java memory / Snappy

You say you start several times. So freeing the JVM memory will probably not help. Because with every run a new JVM is started, with new memory. But you can try to invoke the garbage collection of the JVM. This would look like the following: import jpy System = jpy.get_type(‘java.lang.System’) System.gc() When using readPixels you should consider doing your computation linewise or in tiles and not the whole band at once.
