I see nothing wrong with your first example of queue.
Hold your horses there Bingley. Ben's example states:

IMS has a huge deadletter queue that will be cleared by a coldstart on Sunday

A queue (in this sense) is a temporary holding place for data. For example, a messaging server receives e-mails through MTA from another server and stores the locally until they can be processed (e.g. checked for a virus, categorised etc.) - this is a messaging queue
Queue is also a programming term used to define what order data is processed.
If data is being collected only in order to be purged then it's not a queue because a) it's not being stored in a particular useful order, and b) is not awaiting further processing.
Couldn't it just be called a dead-letter repository, heap or collection? Or to restate the sentence:

IMS is congested with excess dead-letter data that will be cleared by a cold start on Sunday

Never heard of quiese, but one can acquiesce in or to something. Anyway, here some tidbits about queue:

When the British stand in queues (as they have been doing at least since 1837, when this meaning of the word is first recorded in English), they may not realize they form a tail. The French word queue from which the English word is borrowed is a descendant of Latin côda, meaning “tail.” French queue appeared in 1748 in English, referring to a plait of hair hanging down the back of the neck. Latin côda is also the source of Italian coda, which was adopted into English as a musical term (like so many other English musical terms that come from Italian). A coda is thus literally the “tail end” of a movement or composition. (The American Heritage® Dictionary)
