I see you are using Samba 3.0.6. There were a lot of bug fixes after
that release. I would start with version 3.0.14a. I've been using that
version with ClearCase (although with Solaris 8).

I would not use 3.0.20anything or even the latest 3.0.21b.

It might be useful to see your smb.conf as well as your client MVFS
settings. However, ClearCase is not within the scope of this mailing list.
