请教javacore文件的分析.

[dushipianzhou]

我的websphere这段时间会出现进程莫名消失的问题，OS是redhat的.
用jca工具分析了下，觉得主要问题如下，但不太能看的懂，请各位指教应该如何处理：

首先查查SystemOut.log, SystemErr.log, native_out.log, native_err.log文件中是否有可以帮助诊断的信息


检查一下是不是内存好光了，出现了jvm的错误等。

[YuLimin]

你说的是WAS的Java进程消失了，对不？
那就是直接WAS当掉了？
对生成的JavaCore与HeapDump进行分析，打个包发上来看看。

[mingr6370]

把javacore拿上来看看吧，还有systemout

实在不好意思，不知道如何将附件加载上来。
还是很感谢各位，虽然还没解决。。。
