Turns out that one of the older model - a big Naive Bayes classifier - was taking around 50s to We're observing intermittent HTTP 502s in production, which seem to be correlated with the "autorestarting worker after current request" log line, and are less frequent as we increase max_requests. The issue is probably with the parameters you pass to gunicorn. Defaults to 30 seconds which I increased to 300.
