【问题描述】：
出于开发目的，我正在运行本地 WAS 7.0 服务器。我的机器是 Win 7，我使用的是 Java 1.6。 WAS的具体版本是：
IBM WebSphere Application Server, 7.0.0.25
Build Number: cf251235.04
Build Date: 8/30/12
我使用的Eclipse版本是
Eclipse Java EE IDE for Web Developers
Version: Juno Service Release 2
Build id: 20130225-0426
以及 WebSphere Application Server 7.0 Eclipse 插件
com.ibm.websphere.v7.core (7.0.101.v20121205_2240) "WebSphere Application Server v7.0 Core Runtime Jars" [Active]
我遇到的问题是每 2 分钟左右就会在我的 SystemOut.log 文件中打印以下警告：
[9/17/13 16:54:47:812 CDT] 00000025 AlarmThreadMo W UTLS0008W: The return of alarm thread "Non-deferrable Alarm : 2" (0000001f) to the alarm thread pool has been delayed for 40106 milliseconds. This may be preventing normal alarm function within the application server. The alarm listener stack trace is as follows:

这种情况始终如一地发生；因为我收到“延迟”警告，然后 2 分钟后我收到“已完成”警告。然后大约 60 秒过去了，我再次收到“延迟”警告，然后在大约 2 分钟后再次收到“完成”警告......广告无限。
除了可笑的烦人；一切似乎都运行良好......我能够发布/启动/停止服务器。我的应用程序运行正常。
我只是想让这个警告停止填写我的 SystemOut.log...有什么建议吗？
附：我的服务器定义中确实有以下设置作为我的“通用 JVM 参数”：
-Xquickstart -Dcom.ibm.websphere.alarmthreadmonitor.threshold.millis=140000 -Dlog4j.debug-XX:+HeapDumpOnOutOfMemoryError-XX:HeapDumpPath=D:/temp
认为设置“-Dcom.ibm.websphere.alarmthreadmonitor.threshold.millis=140000”应该将警告阈值增加到 140,000 毫秒，而不是默认的 40,000 毫秒（从 here 中发现）
