virtual thread issue with ECS fargate / Kubernetes about spring-boot HOT 1 CLOSED

NOTE: It looks like if there is any I/O operation then virtual thread take place and internal ingress times out. Once I disabled virtual thread it works without any issue.

In both cases, is the same amount of traffic reaching the application (request/sec and concurrency)? I doubt that this is a Spring Boot issue, it's more likely a performance problem with your application. Once the web application accepts an higher number of concurrent requests, you will find other bottlenecks in your application that were previously hidden. In this case, the database connection pool and timeouts configuration are good candidates.

I'll close this issue for now as this type of problem is out of scope for the Spring Boot team. I would suggest profiling your application to check what's going on at runtime.
