Well, I groveled through the commit logs from 8.4.4 to 8.4.7, and
I can't find anything that looks like it could possibly be related.
So at this point I'm inclined to think that the bug is older than
that, but your usage patterns changed so that you started to tickle it.
Can you think of any changes in your usage that might date to around
that time, and would somehow be connected to backend startup/shutdown?
