websphere - 每 60 秒发出一次警报线程警告

Question

我正在运行本地 WAS 7.0 服务器以进行开发。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

和 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，我会在 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:

这种情况一直发生；就像我收到“延迟”警告一样，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“已完成”警告..​​....无止境。

除了可笑地烦人；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满我的 SystemOut.log ......有什么建议吗？

附言在我的服务器定义中，我确实将以下设置为我的“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)

Answer 1

事实证明，我的 JVM 参数中有一个关于 com.ibm.websphere.alarmthreadmonitor.threshold.millis 的拼写错误。属性(property)。

添加 -Dcom.ibm.websphere.alarmthreadmonitor.threshold.millis=140000到我的 JVM args 成功抑制了警告。
