Hello,
after an update from Samba 2.2.12 to 3.0.22 and running the daemons 2-3
days my Samba Server freeze the whole Server.
First the clients get connection problems, timing out to access the shares
and then some minutes later the whole Server freeze, i can't even logon on
the console. Only a cold reset is possible.
I convert all files from latin-1 to a UTF-8 and then from UTF-8 to
ISO-8859-1 (german filenames) with conmv.
It works in ADS mode and kerberos is working fine, also i get the list of
Domain user and groups.
The System ist a Debian 3.1 with ext3 filesystem.
The files lay on a ReiserFS 3.6 with standard journal. Its a RAID 5 System
with a Mylex Controller (DAC960)
The old installation Suse 8.1 with Samba 2.2.12 works without any problems.
In the main smbd.log there are no error messages.
All error message in the log files are from clients:

Any ideas how i can find the failure and fix it?
I guess it has something to do with ReiserFS but i am not sure.
Thanks in advance
