There are two error messages & both meant very serious.  

 

First line means your CPU is flat-lining at a very high level.  What IOS version are you running and how many members are there on a stack? 

 

Next line means that the OS is trying to generate a report and store it in flash but it's full.  

 

2nd line, for me, is critical because if the switch will crash, because the flash is already full, the switch will boot up and crash.  This is call a boot-crash-loop.

Please update us with the info which Leo requested along with the below outputs:

 

show ver

show proc cpu sorted | ex 0.00

show proc cpu history.

sorry for the late replay

and thanks for your answers and suggestions

Congratulations.  You've just solved one (1) problem.  The Flash memory needs to be cleared in case the appliance crashes.
