Errr... well, please, read at end of my email :-)

-------
The number of smbd daemons stalled increases in time.
I'm using FC4 with last updates installed and samba 3.0.21a.

Maybe is a kernel related problem with file locking?

Thanx in advance!

The fact is that I have installed 3.0.21a samba version. FC4's RPMs from
samba.org web, and I get the same behaviour.

Thanx in advance!
