Hej everybody,
hej Erich and KP,

some days are gone and I can put one on top.

After commenting the log-Parameters 'stdout' in hostapd.conf, behaviour 
seemed much better.

Today I wanted to monitor a new dhcp-client with tail -f 
/var/log/dameon.log an found:

# tail -f /var/log/daemon.log

And the log was frozen since more than 12 hours.
What's that "2248 log entries lost"???

# l /var/log/daemon.log
-rw-r-----    1 root     adm         799683 Dec  1 06:44 /var/log/daemon.log

not too big....

# du -h /var/log/
168.0K	/var/log/ntpstats
8.0K	/var/log/lighttpd
10.4M	/var/log/

not too big as well....

not too big but wrong as on the start of the thread....

That's still the old game....
