Unleashed Syslog Messages.

I have master slave setup with Unleashed R550, I am getting this below syslog messages. 
<179> Oct 30 01:38:09 syslog: lwapp_get_sta_stats IEEE80211_RUCKUS_GET_STA_STATS=163 ioctl failed
what does it means? I got an documentation of different syslog messages. 
https://docs.commscope.com/bundle/unleashed-200.10-syslogref/page/GUID-596B496B-F47A-41E7-89CF-C520D...

But I couldn't get an exact match for the above mentioned syslog message.

Hi @WiFi_GURU 

The above error indicates, specific wireless client leaves a BSSID without sending De-authentication packet, controller tries to delete the MAC entry of the client but does not see the client present anymore. 

However this error is harmless and does not confirm any disconnections happening.
