> Does there exist back pressure? Could you please find out it from metrics. The same problem occurs on a 64U128G machine in the production environment. The number of tasks is about 4000, and the scheduling is performed every 5 minutes. The dump.hprof file shows that thousands of instances of the WorkflowExecuteRunnable object are not released. The logs of the master service contain a large number of null pointer exceptions, but the logs do not contain stack information. -- This is an automated message from the Apache Git Service.
