Hi Craig,

 

Here is bt after installing all the missing debuginfo packages.

Please see if this could help in analysing the issue.

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.
