Symptom:
You use the -s option with fnbind and fncreate, but for certain names you get "name in use."
Possible Cause:
fnbind -s and fncreate -soverwrite the existing binding if it already exists; but if the old binding is one that must be kept to avoid orphaned contexts, the operation fails with a "name in use" error because the binding could not be removed. This is done to avoid orphaned contexts.
Diagnosis:
Run the fnlist command on the name to verify that it is a context.
Solution:
Run the fndestroy command to remove the context before running fnbind or fncreate on the same name.
