Until we can find a developer to compile the library, we have a work-around. I found out from another DBA here that this is a known problem - the environment variable LD_PRELOAD was set to point to this library in the custom environment file. Unsetting it allowed the Apps services to start and relink to work. I can test your suggestions myself on the development instance to see what happens.

And how do I fix it?
