I have a PIX 515. I am trying to do a show config on the box. It is giving me an error message saying
"flash device is in use by another task".
I do not know what this means or why it is being displayed.
if another task is using the Flash memory device, such as when two administrators accessing the console from Telnet both issue the show config command, the following message now displays:
The flash device is in use by another task.

Which version of PIX OS is currently running?
