I am not able to find the exact bug for Cisco 3750E stack - Debug Exception (Could be NULL pointer dereference) Exception (0x2000) error.
Closest i can find is CSCsa72400 which only affects ver 12.2(20)SE4.
All the stacks (3 switches) are running 12.2(50)SE3
It appears that the switch 1 crashed and reloaded. My hunch is its software but i cant find any related bugs. It could be hardware issue as well?

The strange thing is there is a crashinfo folder but there is no files in there.
