Not sure if its related to this change: https://github.com/apache/lucene/commit/c8e05c8cd6e018133d3d739d159d5b3b6b29c179#diff-be8459728adce212557bc19afbe0a8b91c788a49b1379323af40e3ba3ec4e479R154 Can you retry after disabling this feature by adding this JVM arg: `"-Dorg.apache.lucene.store.MMapDirectory.enableMemorySegments=false"`

Might be related to https://github.com/opensearch-project/OpenSearch/pull/17502 We can do similar change here: https://github.com/opensearch-project/cross-cluster-replication/blob/main/src/main/kotlin/org/opensearch/replication/repository/RestoreContext.kt#L42

Were you able to mitigate this by using jvm argument shared above? I'll check if this can be fixed for upcoming versions.
