Hi Volker and many thanks for your response
According to your questions
>Please remove the SO_RCVBUF and SO_SNDBUF entries.
>Oh, that's ancient. Do you have any possibility to move to
>"security=user"?
The smb.conf file was inherited from HP-UX system. Ok,
I'll remove them
>Did you try "posix locking = no"? That is mostly criticial

There is no NFS at all over the fs. It is only ACFS + samba. We
tried to disable any interference with posix locks over the ACFS, so the
parameter was set to no. Is it right?

We got the following strace over the samba process 'locked'
