associated clients are dropped and can't associate anymore

[Jan Rovner]

Hello,

I'm using hostap-0.0.4 in Master mode and sometimes
associated clients are silently dropped and can't 
associate with AP anymore.

The only thing that helps is to drop and reload
the driver:

ifconfig wlan0 down
rmmmod hostap_pci
modprobe hostap_pci
iwconfig wlan0 ...
ifconfig wlan0 ...

Does anyone has the same experience?

Maybe a SOFTWARE WATCHDOG could be the workaround
(to periodically monitor whether such situation 
occurred and in the positive case to execute "repair" 
script).

Any idea about this? Does such watchdog exist?

Thank you very much!
Jan
