How could a user encounter the problem that this fixes? I don't understand what was done here. Thanks!

It could happen if there are few disk tables and they are repeatedly dropped and recreated. It is not necessary to have on-going ops when dropped.

Documented bugfix in the NDB-6.2.19, 6.3.29, and 7.0.10 changelogs, as follows: Repeatedly creating and then dropping Disk Data tables could eventually lead to data node failures. Noted that this also fixes BUG#45794. Closed.
