Cause: Federated link Id numbers are assigned sequentially from a list of 64k candidates. After 64k link numbers have been assigned then the number sequence starts again at zero and link Id number collisions occur.
Consequence: Federated links receive errors when trying to create sessions using duplicated Id numbers.
Fix: Keep a list of in-use link Id numbers and do not use that would conflict with existing links.
Result: Federated links may be created and destroyed indefinitely without receiving errors.
