Hi Hans,
This problem is now understood. The standard "setup kai" on cdfsga
where I generate the libraries has changed to point to KAI vesrion 3.3
instead of version 2. Thanks to the help of people at FNAL,
I have now rebuilt a working version (linked with libNew.so).
The Shared memory support in TMapFile is operational again.
You can import the new tar file from our Web site.
