Strace shows the processes waiting in a "read(0, " call; I have never
been able to get more information out of it.

I have even set up a debug-enabled qpopper with strace on a special port
number, but when I told one of our users to actually use that special
port, such hangs never occured again on that special port, so I never got
a detailed log of what happens. Really strange thing!
