1) connection_pool.go: GetConnectionStats read lastRecoveryAttempt (a multi-word time.Time) without any lock while checkAndRecover wrote it under recoveryMutex -> data race on live admin API endpoints. Snapshot it under recoveryMutex (the writer's lock). Regression test TestGetConnectionStatsRace drives the read path concurrent with the locked write under -race. 2) cache/memory memory.go: Cache.Get expired path used an unconditional Delete + atomic decrement, so concurrent Gets on the same expired entry each decremented entryCount/memoryUsage -> permanent negative drift. Use LoadAndDelete-with-guard (as evictOldest/evictToFreeMemory already do) so only the goroutine that actually removes the entry decrements. Regression test TestMemoryCacheConcurrentGetOnExpiredEntry_CountersConsistent.
