Hi Alexandr,
There are a few possible options for what you see there. The first is a summarized version of a core dump created when a process crash occurs. The second is a memory dump generated when the switch reboots due to a kernel oops. Finally, it could show a summary of current memory usage if the switch reboots due to memory depletion.
Essentially, in all three of these cases, there isn't much that a customer can do with the information that is given. It is mostly used by GTAC and our development teams to determine why the switch crashed for any of these three reasons.
Sorry that this probably isn't the answer you were looking for, but there isn't much you can do with this information without access to some of our internal tools.
Let me know if you have any more questions.
