Hi,What is crash info ?

6509 have a log list below:

00:00:33: %C6K_PLATFORM-5-LESS_SPACE: May not have enough space to save the crash info. on flash of Router on module: 1

My questions:

1.What is crash info ?

2.Why 6509 have start crash info ?

3.Why 6509 reload after appear crash info ?


Re: Hi,What is crash info ?

crashinfo is a file that stores information about a previous crash of the software subsystem in the catalyst (any cisco device in general). This file is stored in flash memory in a catalyst. This file will have information like stack traces, which basically holds the information (will have to decoded to reveal this info), why the switch software crashed. This information is generally useful to a Cisco TAC engineer. You are probably running out of space on your flash chip. Check to see if you have any unwanted files (or multiple files stored in flash). If there are files that are deleted and not yet squeezed, squeeze them and try making up more space.

obviously the Flash device does not have enough space and crash information might not be saved.

Check for unnecessary files from the Flash device and enter the squeeze command for the device.

I assume your router has crashed ? Can you post the result of the show stacks command ?

Re: Hi,What is crash info ?

A show stacks decode using Output Interpreter doesnt reveal any sign of a crash. Give a show flash or show bootflash and see if you have any unwanted files (that were deleted but not squeezed). If yes remove them, to make up more space in flash.

Re: Hi,What is crash info ?

Hi,I have a question ,if flash or bootflash no more space ,

Then 6509 would reboot itself frequency ?


Re: Hi,What is crash info ?

No, running out of bootflash shouldn't make the router crash. But it will keep the router from writing a crashinfo file, which would help TAC determine the cause of the crash in the first place.
