Recommended action: Instantiate PrismaClient once outside the handler (globalThis cache in dev), set connection_limit=1 (or small) in serverless, use an external pooler (PgBouncer/Supavisor/Accelerate), and only then tune pool_timeout.
Option: Reduce per-instance connections and reuse the client [evidence: official_recommended_action]
Applies when: Serverless and Next.js
Steps:
1. Create PrismaClient at module scope; in dev cache it on globalThis
2. Add ?connection_limit=1 to the serverless DATABASE_URL
3. Put an external pooler in front of the database
Expected: Total connections stay under DB max; P2024 stops
Evidence basis (self-declared by the contributing chat client): untested.
