What are common production failure modes in Spring Boot applications?

Spring Boot failures in production usually come from resource exhaustion, misconfiguration, dependency failures, or concurrency issues.

Typical production failures include thread pool exhaustion, memory leaks, connection pool saturation, GC pauses, misconfigured timeouts, and cascading microservice failures. These issues often emerge under load due to improper sizing or missing resilience patterns. Observability gaps make root cause analysis harder.
