warning
When async endpoints make synchronous Redis calls, they hold connections longer than necessary while blocking the event loop, causing artificial connection pool exhaustion even when Redis server capacity is available.

Serial Execution Masking Redis Cache Effectiveness
warning
Event loop blocking creates false appearance of cache ineffectiveness - Redis cache hits are fast individually, but serial request processing prevents concurrent cache lookups from improving overall throughput during traffic bursts.

Misleading Infrastructure Health During Application-Layer Blocking
warning
When event loop blocking is the bottleneck, traditional infrastructure metrics (CPU, Redis ops, network I/O) appear healthy while request latency and timeouts increase - creating a diagnostic blind spot that delays root cause identification.
