Perhaps the backend's gotten into some kind of loop, and isn't reaching
the point at which it would realize that the client connection is gone
and then exit. Can you attach to the looping backend with a debugger
and get a stack trace for us?

These are suspicious, but not hard evidence of a problem. IIRC we've
determined that there are legitimate cases where zero pages could get
inserted into a table. See past threads about "Uninitialized page"
