Connection Pool Starvation
A deploy just shipped. Request latency and error rates are climbing, and the database connection pool is pinned near 100% utilization — but traffic hasn't moved and the database's own CPU looks completely normal. Diagnose whether this is demand outgrowing capacity or something the deploy itself changed, and restore healthy throughput without just throwing more compute at the problem.
