ASDM unavail, "The flash device is in use by another task."

[3moloz123]

As of today, when trying to reach asdm on /admin/, I get:

The flash device is in use by another task. The flash device is in use by another task. HTTP/1.1 404 Not Found Date: Thu, 13 Oct 2011 12:19:02 UTC Connection: close Content-Type: text/html

404 Not Found

The requested URL /admin/public/index.html was not found on this server.

Debugging does not reveal more information:

asa01# debug http 255

debug http enabled at level 255.

asa01# HTTP: session verified =  [0]

HTTP: processing GET URL '/admin/public/index.html' from host 81.216.105.126

ASA 8.2 and ASDM 6.31

Can you post a configurtaion from the ASA??

I don't see how it's relevant, I tried with a different ASDM image but with no go. I cannot save config either.

On another forum, it was claimed that a logged in user could cause this somehow, but "who" on the device does not show any logged on users.

I think that one of our technicians might have been using the console cable, and possible left without scrolling until the end of a 'show run' - do you think this might have locked the flash?

[varrao]

Could be possible if another user is logged into the firewall, you would need to verify that. "show asp table socket" might help you.

How can I determine which one it is, and how could it be forced shut?

Hi,

Yes, we can terminate the sessions, by"

First do :

show asdm session

Pick the session from there, and use:

asdm disconnect

This would disconnect the session.

Hi,

Can you paste the output of the below command.

sh flash

[3moloz123]

Thanks,

It proved to be the left and unfinished "show run" by a colleague of mine. He had to go there and manually press space until it quit.

Could the console session have been killed/resetted too somehow?

[varrao]

Not sure if we can terminate thde console session, but you can definitely set a timeout for it by "console timeout ".

I had the same issue which was fixed by rebooting the ASA.
