Hi @Asif Khan

The "F6: Cannot Preempt Item" message is generated by the ADH server. ADH server send this it as a status response when a new request cannot be satisfied because the cache is full and an item cannot be preempted. It could happen because the priority of the requested item is less than the priority of any item in the cache.

You may need to configure the ADH maxCache, preemption parameters. I suggest you contact the TREP support team for more detail.
