I have been having some serious issues with my 1121G APs over the past few days. I recently upgraded to 12.3-7 and for unknown reasons the AP's are creating r12-*****.rcore files. These files will fill the AP's flash memory and render them useless, you can ping them but not telnet. The only fix I have been able to get to work is power cycle the AP, login and delete the files, then run a fsck flash and do a wri erase and reboot the ap again. I have the command "no exception crashinfo" to take care of crash files doing the same thing. Is there any way to stop these .rcore files from being created? I would also like to know why they are created.
I have uploaded my current config if you wish to view it.
