samba - Sep 2004 - Upgrade 3.0.5 to 3.0.6 causes client hang on file access

Hi,

Chris Mills opened already a very similar thread:
http://lists.samba.org/archive/samba/2004-September/091704.html

The reason why I open a new thread is, because it happened at upgrading 
from 3.0.5 to 3.0.6. 
For the time being I downgraded to keep the system working but I have to 
find another solution soon ... 

It happend to me at two computer, both using Debian, one 2.4.18 the 
other 2.4.20 (this one self compiled).

It's working with 3.0.5-1 and errors with 3.0.6-3.

Error description: 

At the client (WinXP) I can browse but as soon as I want to access a 
file, the explorer hangs.

I would really appreciate your help.

Thanks
Florian.

Try setting "use sendfile = no" in your smb.conf.
Might be a bug in Kernel 2.4.x sendfile.

It appears from bugs on the debian BTS that this is the case.  The
kernel 2.4.20 in particular has been mentioned.
