Was the blocking you described occurring at the time you captured
this? It doesn't seem to be showing any problem.

A minor release (where the version number doesn't change before the
second dot) never requires a dump and restore. There is sometimes a
need to do some cleanup work; for example, if a bug is fixed which
could corrupt a particular type of index, the release notes may
recommend rebuilding all indexes of that type to repair any damage
which may have occurred before the bug was fixed.
