Issue with global variables "disappearing"

Hi All,

I have strange issue with global variables, after some time all set of variables are gone from the environment, there are no router reboots happening, I have no idea what is causing it and my understanding is that the global variable is preserved for the whole uptime of the router - is it not the case?

RB in question: KNOT, RB924i-2nD-BT5&BG77 fw: 6.49beta54.

Kind regards,
Adam

When console crash, all variables are deleted because all environment restart from zero.
Search on logs the crash or the existance of console-dump.txt or similar names on files.
