This happened to me yesterday, moving WildFly Core project (68 modules) from wildfly-staging to releases repo.

The staging-move goal took a lot of time. I left the laptop running during the night. The artifacts were all successfully moved, but the client maven gola execution never ended, and I had to close it forcibly with CTRL-C

At that point, the client did not get any feedback on whether the movement completed successfully or not, so you are forced to check the tag and verify that all the artifacts were moved before closing the client.
