APAR status

  • Closed as program error.

Error description

  • Error Message: When a customer is using jdmpview or DTFJ to
    analyse a Linux core dump they may see only the top stack frame
    for each native thread.
    .
    Stack Trace: N/A
    .
    

Local fix

  • Native tools such as gdb may be able to provide full stack
    frames for native threads if they are run against the core file
    on the original machine.
    

Problem summary

  • The problem was caused by limitations in the stack walking code
    used with Linux core dumps.
    

Problem conclusion

  • The native stack walking code has been updated and is now able
    to walk the native stacks.
