每隔60秒发出警报线程警告

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

我正在使用的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分钟左右我收到以下警告打印到我的SystemOut.log文件:

[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 就像在我得到'延迟'警告然后2分钟后我得到'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分钟后再次发出"完成"警告..​​....无限制地.

除了可笑的烦人之外; 一切似乎都运行良好......我能够发布/启动/停止服务器.我的应用程序正常运行

我只是希望这个警告停止填写我的SystemOut.log ...任何建议？

PS我的服务器定义中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

设置'-Dcom.ibm.websphere.alarmthreadmonitor.threshold.millis = 140000'的想法应该将警告阈值增加到140,000毫秒而不是默认值40,000毫秒(从这里发现)

Answer 1

原来我的JVM args中有关于该com.ibm.websphere.alarmthreadmonitor.threshold.millis属性的拼写错误.

添加-Dcom.ibm.websphere.alarmthreadmonitor.threshold.millis=140000到我的JVM args会成功抑制警告.
