<p>Ugh, really? Is anyone else continuing to see 502s, or 500s of any sort? If yes, then we have some more digging to do, although now we at least know where to look. If not, then I can work with Fred to see what might be causing the errors just for him.<br>
I've done a full reset of all the servers, so maybe that will have a good effect. When in doubt, restart a server.<br>
Please continue to let me know if you see 50x errors.</p>
