感谢您对此问题提供的专家帮助。
同一台机器上运行的两个 weblogic 管理节点有一天宕机了，在尝试使用重新启动它们时startManagedWebLogic.sh，发现 Weblogic 卡在了语句上。
<Nov 17, 2015 12:11:29 AM UTC> <Info> <WorkManager> <BEA-002900> <Initializing self-tuning thread pool>
在两个节点上都观察到了这种行为。
运行 aPS -3 PID产生了以下线程转储。运行 3、4 次后，每次都能在线程转储中观察到该方法的存在。
weblogic/diagnostics/flightrecorder/FlightRecorderManager.isRecordingPossible(FlightRecorderManager.java:181)
非常感谢任何关于解决该问题并启动 weblogic 节点的指示。
下面给出了线程转储以供参考。

谢谢并问候 Jimmi
答案1
最后，我们找到了一种启动 weblogic 节点的方法。这里有一些可能对其他人也有帮助的数据。
根本原因
我们所面临的问题的根本原因被发布为问题，与 /tmp 文件夹的权限有关。
托管这些 weblogic 节点的机器已/tmp重置文件夹权限，如下所示
drw-r--r-- 10 root root 4096 Nov 20 00:00 tmp
当节点早些时候工作时，权限被设置为
drwxrwxrwt 36 root root 20480 Nov 20 00:24 tmp
Weblogic 进程使用 root 以外的用户启动。
看起来这个更改权限导致节点关闭，然后阻止它们重新启动。
解决方案
由于我没有根访问权限，因此无法重置权限。
java.io.tmpdir目前，通过将 jvm 所需的临时文件夹指向 weblogic 用户可以访问的另一个文件夹，并在文件中设置 JVM 属性来启动节点$DOMAIN_HOME/bin/setDomainEnv.sh
例子：
-Djava.io.tmpdir=/home/weblogic/tmp
