Hi @gvmarozzi. This can happen for a number of reasons and hard to say without some details on the actual realm usage. Realm files are mapped to memory when opened, so it is most probably due to a growing realm file. This is usually a version pinning issue where a Realm instance is not closed properly or when the realm is instantiated in a non-looper thread.

You can see more about the realm instance life cycle at https://www.mongodb.com/docs/realm/sdk/java/realm-files/open-and-close-a-realm/

Can you provide more details about you realm usage?

Closing due to missing feedback.
