问题
I had a tomcat crash on live server , which generated hs_err_pid file .In this there is a Problematic frame -> _wordcopy_fwd_dest_aligned+0x54. I searched in all similar cases of jvm crash but couldn't find whats the meaning of this problematic frame.Any suggestions ?

- Crash you observed is not a java issue it is redhat issue
"https://bugzilla.redhat.com/show_bug.cgi?id=546158" - What is Problematic Frame: It is the top frame resulted in the crash, in your case it is native frame (C) resulted in libC.so file. Please find more details here
回答2:
There are several possibilities, here. But unless you are using any native libraries (e.g. tcnative), the fault lies completely outside the application (including Tomcat here as part of "the application"). Nothing the application can do should cause the JVM to crash.
- There is a bug in a native library you are using
- There is a bug in the JVM
- There is a bug in
libc - You have a hardware error
I think that #1 is the most likely if you actually have any native components.
I think #4 is the most likely if you do not have any native components. Every time I've ever seen a SIGBUS it has turned out to be a problem with the underlying hardware. If possible, take that machine out of service and run memtest86+ (or equivalent for your architecture) on the machine. It will exercise the memory, CPU, the system bus to see if working them constantly can expose a problem.
If your system passes 2 tests of memtest86+, I'd say that you have more likely found a bug in the JVM (unlikely) or in libc (even less likely). In either of these cases, upgrade everything to the latest versions and re-try.
