Hi
One of my AIR-CAP3502I-E-K9 just crashed. It rebooted itself and came back to service.
In the logs I see this here:
*Mar 1 00:00:09.669: *** CRASH_LOG = YES
*Mar 1 00:00:09.971: soap_extern_intr_dispatch: no handler for UIC2 intrno 12 level 4
*Mar 1 00:00:10.270: soap_extern_intr_dispatch: no handler for UIC2 intrno 12 level 4Security Core found. (no idea if this is important)

Now a dir flash: doesn't show a crashfile anymore:

Anybody knows where I could find the complete crashlog and if this is maybe a known bug? It's not in the configured TFTP folder.
The controller is running 7.0.98.0.
Thanks

If we assume that you are facing a known bug that is fixed an engineering special of 7.0, you would need anyway to open a tac case. And if it's a new bug ... you should also open one :-)

Found the crashfile on the controller (under Management -> Tech Support -> AP Crash Log)
So far it's rare enough that an engineering build isn't worth the effort of upgrading my 4 controllers.
It happend on 3 (of +80) APs in the last 5 months, that's so far ok.
But I still hope that Cisco will soon release a new build, because of some DHCP bugs in the current build.

Been there. Done that.
I have about >250 units of 3502 and I have about <10 units crashing. All show the same symptoms:
1. One of the two radios would "disappear". I'm not saying it would go down but the 2nd radio would not be there in the interface tab of the WLC.
2. The presence of the "sensord_CSPRNGn" file(s) and/or crashinfo.
My only solution was to reload the AP's and everything comes good.
