[Bug][Master Dispatch] Master Dispatch Task Instance Failed

[sunshining93]

After using Dolphin Scheduler to create a simple work flow that contains some tasks, few tasks can not run in time when the timer tasks trigger.
In this case, master node and worker node load avg is very low, it seems like this always happens when the Netty Error occurs.
In the work flow, the task instance is Submit Success status, but can not get any Log Info in execute worker node, this situation lasts until task instance time out.

Please help to confirm whether this bug is related to Netty Error and fix this BUG

Dolphin Scheduler Version is 1.3.6
master(12c 24g) property:
master.exec.task.num=50;
master.dispatch.task.num = 100;
worker(32c 64g) property is default

By Analyzing the worker node log, The worker node normally execute 4-5 tasks at the same schedule time
