Thomas, The 2.2. branch is no linger under development or
maintenance.  However at the very least I would suggest
upgrading to to Samba 2.2.9.  I remember this code and when
Jeremy was working on it.  Changes are that 2.2.9 will be
better for you.

I don't remember the Solaris lock kernel bug was Solaris 7,
8, or 9 (or all three).  But check with you Sun rep about the
fcntl() kernel lock patch.  Don't remember the patch # right now.  Sorry.





cheers, jerry
