The Cisco Access Point (AP) hangs until power-cycled and does not crash. While in a hung state, the AP does not respond on the console or Telnet. After the AP is re-set, there is no crash info, and it shows the last reload by power on. When the Wireless LAN Solution Engine (WLSE) and the Multi Router Traffic Grapher (MRTG) are used, there is no increase in CPU or memory utilization before or at the time the hang starts.
This issue is documented in Cisco bug ID CSCsc01706. Also, refer the Cisco bug ID CSCsc33052 if the issue is related to a memory problem.The hang only occurs on the Wireless Domain Services (WDS) AP. This problem occurs when there are many wireless clients that attempt to associate or roam. This problem is introduced in 12.3(4)JA, but most problems are reported in 12.3(7)JA. This issue is fixed in software versions 12.3(7)JA2 and 12.3(8)JA . In order to resolve this issue, upgrade the Cisco IOS image in the AP.
Refer to Wireless Domain Services Configuration for more information on how to configure WDS. Refer to the Working with Software Images section of Managing Firmware and Configurations for more information on how to upgrade the Cisco IOS image in the AP.
