thanks a lot EtherMAN,
so if the file or dump exist and if we can see it with the following command
show debug system-dump
we are not going to be able to read because is a dump and the only people who can read it is GTAC and extreme developers, so i thinks we have to scalate this problem to the GTAC to solve this.
Thanks a lot for your time and help
you are the best, Best Regards
