Tomcat Log4j即使没有要写入的内容，也要继续写入日志文件？

我在tomcat服务器上部署了一个web应用程序。 我使用log4j进行日志记录。它工作得很好。 但问题是，当什么都没有发生时，log4j会不断地将以下内容写入日志文件：

[DEBUG] 2016-03-09 09:13:46,617 com.mchange.v2.async.ThreadPoolAsynchronousRunner - com.mchange.v2.async.ThreadPoolAsynchronousRunner$DeadlockDetector@1f3e145e -- Running DeadlockDetector[Exiting. No pending tasks.]

我不希望这些消息出现在日志文件中

---

有什么解决方案吗？

除了上面的消息外，log4j还写了一些其他消息，但什么都没有发生。所以日志文件在增长，看起来很尴尬。 我将阈值从

DEBUG

更改为

INFO

。 它解决了我的问题，我的日志现在看起来很干净
