These are on an nfs mounted file system. What could cause this and is
this something to worry about?

Don't know yet. It is unusual - the first message means it can't
find the open file mode entry that should exist for every open file.
Any chance of more context ?

Here is what I could find. The iso file is created on a Solaris system on
a file system that is NFS mounted from our main file server. Then it is
burned to a CD on a Windows 7 PC through a Samba server running on a
different Solaris machine (Solaris 10) that is also NFS mounting the
file system.

As a test I have tried accessing a newly created iso file created on the
machine that created the subject file and then accessed through the same
Samba server. I can not duplicate the messages. I did not burn the file
to a CD but instad copied it to another location.
