Thanks for responses,

The filesystem is OK; we used mkfile to create a 3GB file with no errors.

Will try the truss suggestion...

Thanks,
Drew.

Drew,

It sounds like a large file problem with you OS.  Can you crate a file which
is larger than 2 GB on your filesystem?  If not, then I bet that scanner is
failing because the write failed.  You can verify this by running scanner
through truss and seeing exactly what write failed.  I am betting that it is
the write to the temporary file, nsrscan......
