hostapd groupkey problem with madwifi

[Whoopie]

Hi,
after the connection breaks I get these message on the console. Didn?t see 
it because I used Putty to connect to the linux AP.

Jan 16 16:04:59 server kernel: 0xc4fe6200: mac 00:0e:35:50:5b:ad refcnt 1

These messages appear several times in /var/log/messages.
Could this be an indication for the connection break-down?

Kind Regards,
Whoopie
