ruanwenjun opened a new issue #5161:
URL: https://github.com/apache/incubator-dolphinscheduler/issues/5161
**Describe the question**
code in LoggerRequestProcessor.java
When the corePoolSize equals maximumPoolSize in the threadpool then the
keepAliveTime is invalided.
```java
public LoggerRequestProcessor() {
this.executor = new ThreadPoolExecutor(4, 4, 10, TimeUnit.SECONDS,
new LinkedBlockingQueue<>(100));
}
```
So it is suggested to use Executors.newFixedThreadPool() to create the
threadpool there to avoid confusion.
By the way, this processor mainly handles some io operations, maybe it is
better to set number of threads to twice the number of cpu cores.
```java
public LoggerRequestProcessor() {
this.executor = Executors.newFixedThreadPool(Constants.CPUS * 2);
}
```
**Which version of DolphinScheduler:**
-[1.3.6]
-[dev]
