Critical System Event on WLC

[muhammad-noman]

Hai,

We have installed Cisco WLC 5508, from the last few days we have been observing Critical System Event being continuously fired on Cisco WLC. The error is as under

*spamApTask4: Jun 26 10:39:42.438: %OSAPI-5-OSAPI_INVALID_TIMER: Failed to retrive timer.

Can any one please help us out in finding the cause of that error and any suggestions how we may mitigate that error.

Regards,

Muhammad Noman
