    Description

      Running a nodetool repair -pr --full on a keyspace with a few hundred tables will cause a direct memory OOM, or lots of heap pressure with use_offheap_merkle_trees: false. Adjusting repair_session_space_in_mb does not seem to help. From an initial look at a heap dump, it appears to node is holding many remote trees in memory.
