   > spark.gluten.sql.columnar.backend.velox.asyncTimeoutOnTaskStopping=120000 We also encountered the same issue. After adjusting the parameter mentioned above to 120 seconds, the problem was resolved. our problem job stage has 12000+ task， and each task has multi input split file
   
   Looks like it related to prefetch and async data load, async load hold table scan memory pool, it's release time may be delayed, not memory leak
