Messages have been enqueued and dequeued messages successfully from a queue within the same session.

The no_wait option has been specifie as a dequeue option.

Subsequent dequeues of messages which are enqueued from the same session return the error:

ORA-25228 "timeout or end-of-fetch during message dequeue from <USER>.<QUEUE_NAME>"

The following query reveals that messages are in the ready state for the queue:

select distinct msg_state from <USER>.aq$<QUEUE_TABLE_NAME> where queue = '<QUEUE_NAME>';

where <QUEUE_TABLE_NAME> is the queue table associated with the <QUEUE_NAME>  (dba_queues).

Logging  into another session as the same user and the dequeue succeeds without error.

The same error is reported whether you use a multiple or single-consumer queue.
