ASA 5550 issues

Dear all,


I’ve configured 2 ASA 5550 active / standby (both with SFP module), they work very well when both of them are connected but as soon as I switch off one of them (to test the failover) then the running one tells me “ can’t find mate “ which is right but then it starts to show me a lot of errors / over 100  (in hex ) like addresses and after about 2-3 minutes it says “ damping errors to flash” and it reboots. This continues to happen until I unplug all connections (outside, inside, Lan failover and failover state).

After that it stops to reboot in loop and I can disable the failover in conf t.


Just to make it clear;


  1. If  both ASA are connected then they work fine in failover/standby mode
  2. If  I switch of one of them (failover scenario) then the other one does the case above
  3. If I use only one (after disabling the failover mode in config mode) then it works fine but I don’t have a failover.


The IOS ids 8.2, I have no idea what’s going on.


I hope I will get an answer or fix for it.


Many thanks

If you are still on an early 8.2 release, then first upgrade to 8.2(5) or even one of the last 8.2 interim-releases. Things like these often happen through bugs in the software and you want to rule that out first.

Many thanks Karsten, I've already the 8.2(5), please have a look at the sh version from the ASA 5550:

Many thanks again


Ok, I wouldn't expect too man FO-related bugs in that release. Still I would give a newer version a try. 825-51 is the newest interims-release for 8.2, If you plan to use this device for a longer time, I would also consider upgrading to 8.4.

But with that problem on actual software, the next thing to do is to open a TAC-case for this.

Many thanks Karsten, will do.


Have a nice day


As per you initial description of the issue , I think the ASA device is crashing and you are able to recreate this issue as well.

It would e best to open a TAC case and the TAC CSE would be able to provide you with the fix as well.

Thanks and Regards,

Many thanks for the prompt reply.


Spoke to cisco and they recomend to format the flash and reload everything back, so I've saved the license kay and the config.

I would like to try this on a new flash card (4GB) and not touch the existing one,

I know I could use ftp/ tftp and send the files over to the new card but I would like to open the device and replace the existing card with the new one. my question: can I just format the new card (FAT) and save the IOS (say the 8.2(5)) and  the config file on it by using usb card reader and  pc, insert the card in the ASA and switch it on?.


The other question  please; could I use any make of CF ? e.g. kingston or sandisk or, or


Many thanks
