I'm not sure about the invalid token part... But once I saw this happen
in a test environment where the udf was already proved to be working in
another test environment. We found that the udf library and function
point was fine and was actually installed on the server. But the udf
was dependent on another library (.so file) that wasn't on the server.
We found this by opening the actual binary in vi and I saw that it was
looking for other libraries and that we were missing one of them. Once
the missing library file was put there it worked fine. Not sure if this
is your situation, but thought I would throw it out there.
