I have an 1142 CAPWAP AP running IOS 12.4(25e)JA$ on a 2504 controller running 7.2.103 that's frequently reloading. NCS is reporting the reason for the reload as 'AP Crashed Due To Software Failure'. Other 1142 APs on the same controller aren't experiencing any problems. The AP is in H-REAP mode with local switching but central auth.
Any suggestions for how to troubleshoot this problem would be much appreciated!
Thanks,
Sean

I have never seen this before.
Judging from the from the high mount of Tracebacks it's either a software or hardware bug. Now here's where things get alot murky (for me, that is).
The crashinfo is helpful because it tells me that there was a "Software forced crash". But your WAP is running the latest code from the controller (7.2.103.0) so this is unlikely to be the case since this is the only WAP that's affected.
This now points to a possible hardware error.
However, you could try something else: Try upgrading the bootstrap of your WAP to 12.4(23c)JA1 and see if you can find some improvements.

Either console or telnet/SSH into the WAP. If it "crashed due to software failure", there should be a bucket-full of "crashinfo" files and subdirectories.
Post three of the latest here so we can help you troubleshoot.
Be also prepared to send a replacement.

Funnily enough, I tried that yesterday morning I'll report back if I see any further crashes following the boot update - thanks for your help!

No issues since updating the boot ROM, so I've marked your answer correct. Thanks for the help!

The command is "copy tftp://

Thanks for your reply.
I have put this command without success, it seems that there isn't commands copy or tftp.
Regards.

it seems that there isn't commands copy or tftp.
That's because your AP is most likely running controller-based (aka CAPWAP) IOS.
Do these commands first:
1. debug capwap client enable
2. debug capwap console enable
3. copy tftp://
