- Copy the dump to a machine running similar CCX version.
- run 'gdb -c <core file path> <exe path>' (exe path is the path of the service executable)
- Executable name would be part of the dump file name (core.19841.6.UCCX_Engine.1267009557)
- Executable file path of a few CCX services
- Engine : /opt/cisco/uccx/bin/UCCX_Engine
- CVD : /opt/cisco/uccx/bin/UCCX_Cvd
- etc
- Output of gdb would be something similar
gdb -c /var/log/active/core/core.19841.6.UCCX_Engine.1267009557 /opt/cisco/uccx/bin/UCCX_Engine

- Report to DE and provide the stack trace and the core dump file.
- DE would debug the problematic code reported in the stack trace.
