If the user's job parameter configuration is very unreasonable, with very small but numerous blocks, it can cause a large accumulation of `LinkedList$Node` objects. This can ultimately lead to severe garbage collection issues on the server side, and even out-of-heap-memory errors. -- This is an automated message from the Apache Git Service.
