core dump 或者 crash dump
core dump:A core dump or a crash dump is a memory snapshot of a running process.
如何获得:
- A core dump can be automatically created by the operating system
when a fatal or unhandled error (for example, signal or system
exception) occurs. - or can be forced by means of system-provided command-line utilities.
kill -6
on Linux or Solaris systems 将会强制产生一个core 文件,即使程序无响应。 更多如何获得 参看 [这里][1]
IBM JVM(J9) 的javacore 文件和一般进程的core dump 不是一回事。
