Other than posting here, what research have you done? Did you search for 'uncommitted messages' for example?

By definition, uncommitted messages that are put to a queue are only visible to the app that has the active UOW. The app can either Commit (messages become visible to other apps -- they can then consume / delete them), or the app can Backout (the messages disappear).

An app can also consume messages in a UOW. The app can either Commit (messages are removed from the queue), or the app can Backout (the messages become visible again to other apps).

The current depth of a queue includes uncommitted messages, so its plausible to have a non-zero depth, yet there are no messages that can be consumed.

How to determine if a WebSphere MQ queue has messages that are being held in an open transaction by an application (uncommitted messages)

How do you tell if there are uncommitted messages on a queue?
