There is nothing to do with locale. The same database has been working
just fine for 2 years. Why should this be an issue now?
When I ran the EXPLAIN SELECT, the database was hanging. Or taking too
much time (waiting for 5 minutes), or whatever. I cancelled it.
That's the problem. It works, then it doesn't. Then it works again. I
am guessing it could be the load, but there's nothing new in terms of
load that should be causing this!
