I am asking this as two wireless access points Aironet1142n's have suddenly stopped working at the same time, I am investigating the following two errors that are occuring on them, not sure if 1 is causing the other:

1. Memory allocation of 4676 bytes failed from 0xFDE94, alignment 4

2. Interface Dot11Radio0, Deauthenticating Station 64b9.e861.71c3 Reason: Sending station has left the BSS

Have you seen this before ?? Thanks in advance

It means that client "0022.fac2.350c" has left the wireless coverage area or powered off the wireless NIC.

What IOS are you running?

Hi leolahoo,

Here are the details, I am using as standalone:

Product/Model Number:AIR-AP1142N-E-K9  

System Software Filename:c1140-k9w7-tar.124-21a.JA1  

System Software Version:12.4(21a)JA1  

Bootloader Version:12.4(18a)JA3

Thanks

Try 12.4(21a)JY.

Did   you try rebooting the AP.

Hi Sparthip,

Yes I have rebooted and I could get a client connected, but then the error messages start appearing the logs again and no-one can connect.

The strange thing is that it has happened to two new 1142n AP's that i have bought recently at the same time ?

in the show logs output are able to see any tracebacks generated?

Hi Surendra,

Please find attached the "show memory" command when I have telnetted onto AP, also I have downloaded tech support info aswell.

Is this what you are asking about when you say  show logs output or is there another particular command ?

Thanks

it will be great if you could upgrade the AP software to the latest (i guess its 12.4(21a)JY). i request you to let me know if we are facing the issue on the latest..

Let me know how this works out for you!!
