Windows allows specifying how a file will be shared with other processes when it is opened. Sharing violations occur when a file is opened by a different process using options that violate the share settings specified by other processes. This parameter causes smbd to act as a Windows server does, and defer returning a "sharing violation" error message for up to one second, allowing the client to close the file causing the violation in the meantime. UNIX by default does not have this behaviour. There should be no reason to turn off this parameter, as it is designed to enable Samba to more correctly emulate Windows. True
