Hi Craig,
Here is bt after installing all the missing debuginfo packages.

Hi Craig,
The scenario is lock and unlock of the system for 30 times. During this
scenario 5 sh-QUIT core is generated. GDB of 5 core is pointing to different
locations.
I have attached output for 2 such instance.
You seem to be missing debug symbols. Install appropriate debuginfo packages.
