I see tons of request errors on one of my frontend proxies (on the order of a few per second), but I can't figure out what's causing them. I've tried using the "show errors" command on the stats socket...
echo "show errors" | socat unix-connect:/var/run/haproxy.stat stdio
But this returns nothing. Debug logging doesn't give me any hints either. Is there some other place I should be looking?
Edit: Just to clarify, there is no "error message" per se (though it would sure help to have one). I'm just looking at the counter labeled "request errors" in the web interface and the socat output, and I'm trying to figure out what's incrementing it.
