查询metlink发现是bug：
Bug 7680907  ORA-600 [kclexpandlock_2] in LMS / instance crash. Incorrect locks in RAC. ORA-600 [3020] in recovery

In a RAC environment non contiguous multiblock reads with prefetching
across multiple files may not get the correct locks leading to
internal errors such as ORA-600 [kclexpandlock_2].

问题：是不是只有升级才能解决该问题？
      为什么只有节点二回出现呢，相同的版本，节点一怎么不会出现呢？
      有没有什么避免的方法？
  trace文件稍后上传

就trace看当时lms在等ges remote message ，相关的信息指向 pkey 101954

是否有该对象被drop了的可能性？

为什么只有2节点发生该问题==》可能涉及到的gcs resource master在1节点上导致2节点访问时发生该问题

==》

如何解决？

1. 打补丁 Unpublished bug 5843468 is fixed in 10.2.0.5 and 11g.

2. 找出相关对象想办法workaround

因为是生产系统，所以暂时不能停机打补丁。请问有什么好的方法可以找到这个对象吗？
