When you're using plan tasks performed not closing threads (not) be returned to the thread pool?

- XX: + HeapDumpOnOutOfMemoryError
At the time of memory save memory snapshot, and then to analyze and see what's causing the oom,
CodePudding user response:
To find out why, is because the application requires more resources, the allocation of less, or the code has a memory leak problem,
