  • Cisco 5500 Series Wireless Controllers

Known Affected Releases

7.0(240.0) 7.4(110.0) 7.5(102.0)

Description (partial)

Wireless LAN Controller may encounter unexpected reload without crash file or coredump.
Console log output may include "reaperWatcher rebooting" and "!!!!! Watchdog detected LOCKUP !!!!!",
and there may be "#OSAPI-2-REAPER_WATCHER_INFO" message in syslog.

As a consequence, If we happen to hit this issue during an incremental config save, we may experience corruption or loss of some configs. If this was triggered while saving a config subsequent to a clear config or from the initial config wizard, we may end up losing all of the configs.
And if we hit this issue during a transfer download, depending on the phase of the process, we may endup corrupting an image or the ap bundle.

Affected S/N: 
5508: FCW1614xxxx and later
WiSM2:SAL15129XXX and later

This is due to incompatibility of previous driver with some of the flash components used after that date
