[AusNOG] Cisco ASA 5540

[Pinkerton, Eric]

I have never heard of anything like this, log a TAC case, check your Syslogs, and make sure your console port is secure.

Either..
The flash is bad (if they both rolled of the production line on the same day, I guess it's possible that they are both faulty)
A software bug, is causing the same outcome on both the primary and secondary.

If this were malicious, then I would think it unlikely that the flash would appear physically stuffed (I would put this option aside until you can disprove the first two! - Occcams razor and all that)

Cisco should know from experience if there is a known hardware issue, or a bug, If they draw a blank, then I would be pushing hard to RMA at least one of the boxes asap, so they can analyse the flash and see if it holds any clues, and you can isolate the hardware being at fault.

Also if it's possible in your environment, have a look at what s/ware upgrades are out there - it may happen faster than a physical swap out depending on your circumstances.

Has anyone had an experience with these devices randomly 'locking' and upon a reboot ending up in rommon?

Just had a clustered pair go both at once, apparently its the second time in 4 months.
After reboot the flash was blank and stuffed (0b free space)
After formatting the INT flash card i was able to rebuild them but seems weird. I cannot discount that someone else might be messing with them, because to me this doesn't seem like it would be possible for a cisco product.
