at weblogic.work.ExecuteThread.run(ExecuteThread.java:173) --------------------编程问答-------------------- JavaCore一般用来分析死锁原因，很难用于分析内存占满原因的。。。
建议你用JDK自带的 jvisualvm.exe 来跟踪下内存对象的增长情况。
或者用JProfiler来跟踪对象增长情况也行。 --------------------编程问答-------------------- 对了，建议打开JVM的GC日志，如果是做压力测试的话，可以看看具体是在压哪个功能时，GC所能回收的内存越来越少，直到OOM。
也可以配置JVM在发生OOM时生成 HeapDump，可用来分析OOM时对象数量，但其实难度也比较大。 --------------------编程问答--------------------
系统24小时运行，就害怕影响用户业务的，你说上面的这种配置JVM方法可以尝试一下，我估计作用不大。 --------------------编程问答-------------------- "[ACTIVE] ExecuteThread: '15' for queue: 'weblogic.kernel.Default (self-tuning)'" daemon prio=3 tid=0x02888400 nid=0x83 runnable [0x2427d000]

用 jvisualvm.exe 或者 JProfiler 来跟踪下吧，不过确实会较大降低系统速度。
即便是7×24的生产系统，也可以挑选凌晨来做一些跟踪和测试的。 --------------------编程问答--------------------
只能凌晨跟踪搞了，单从core文件看，就是系统的架构师也很难分析出来。 --------------------编程问答-------------------- 内存占满了，你抓线程数据有啥用？得用 jmap 和 jhap 来抓啊！
补充：Java , Web 开发
