Overview
Emsyne Technologies is an IT services firm modernizing a 10–15 year old legacy financial application for a banking client. The application was experiencing intermittent 10-second Redis connection timeouts causing service disruptions as the platform prepared to scale for new branch onboarding.
Challenge
Redis timeout errors were creating service-level failures under high-concurrency load. The engineering team suspected infrastructure issues, but the root cause was unclear — and the business timeline required a resolution before the next phase of branch rollouts began.
Environment
Legacy .NET microservices application; Redis used for caching; cloud-hosted; approaching scale-up for new banking branches.
Approach
AceMQ performed a structured root cause analysis of the Redis timeout pattern, reviewing connection pool configuration, client-side resource allocation, and concurrency behavior. The analysis confirmed that timeouts were caused by client-side connection exhaustion rather than Redis server capacity issues. AceMQ delivered a remediation plan with configuration changes and architectural recommendations for the scaling phase.
Solution
- Root cause analysis identifying client-side connection pool exhaustion as the primary timeout driver
- Redis client configuration remediation plan (connection pool sizing, timeout tuning, retry policies)
- Architectural recommendations for Redis usage patterns in high-concurrency microservices
- Scaling guidance aligned with upcoming banking branch onboarding timeline
Outcome
AceMQ identified the underlying cause of the Redis timeouts and provided a concrete remediation path, enabling Emsyne Technologies to address the issue before the next banking branch rollout.
