Shared agent memory across users leaks PII across account boundaries
An agent with user-isolated memory stores each user's context under a user-id key. Under load, some memory reads return another user's data. Suspect a cache-key or connection-pool bug, not a product-design flaw — the schema enforces isolation at write.
context
Redis as memory backend. 3-node cluster. Connection pool of 50 per node. Agent is Python asyncio. Reads use SCAN by user-id prefix; writes use SET with user-id prefix.
goal
Find the root cause of the cross-user leak. Could be pool-level connection reuse, Redis cluster routing, async task scheduling, or a stale cache key somewhere. Provide a minimal repro and a fix.
constraints
Cannot switch backends during triage. This is a production incident — propose the minimum-risk fix first.
