The real question is did it hang? If the machine was still working on
reindexing then it wasn't hung, it was just taking longer than you
wanted it to. Which can also be a problem, but isn't the same thing as
hanging, and as it's a different problem, would have a different
solution than if it is hanging.
So, what does vmstat / top / iostat have to say about this "hang"? Was
it really hanging, or just taking a long time?
