I have a Spring-boot application deployed in docker container within in AWS ECS cluster.
My application stack is => Spring Boot -- JPA -- MySQL RDS
Initially application is deployed and accessible through EC2 public IP.
But after few minutes only application is Shutting down ExecutorService 'applicationTaskExecutor' and restart container again. it is happening constantly in every 3/4 mins.
I am not getting this kind of error in local deployment connecting to same RDS.
Here is my application.properties
server.port=8192
spring.datasource.url=jdbc:mysql://multichannelappdatabase.cvjsdfsdfsdfsfs.us-east-1.rds.amazonaws.com:3306/multichannelappdb
spring.datasource.username=xxxxx
spring.datasource.password=xxxxx
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jackson.serialization.FAIL_ON_EMPTY_BEANS=false
spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
spring.jpa.show-sql=true
#spring.jpa.hibernate.ddl-auto=create
spring.datasource.testWhileIdle = true
spring.datasource.timeBetweenEvictionRunsMillis = 10000
spring.datasource.tomcat.testOnBorrow=true
spring.datasource.tomcat.validationQuery=SELECT 1
and here is my cloudwatch log

To properly shut down an ExecutorService, we have the shutdown() and shutdownNow() APIs. The shutdown() method doesn't cause immediate destruction of the ExecutorService. It will make the ExecutorService stop accepting new tasks and shut down after all running threads finish their current work: executorService.
When finished using an ExecutorService , you need to shut it down explicitly. From its javadoc: "An unused ExecutorService should be shut down to allow reclamation of its resources." Calling shutdown initiates a gradual and orderly shutdown.
We know that a Spring Boot web app needs an embedded servlet container on the classpath. The app will shut down if it doesn't find any of the embedded servlet containers. To resolve the unexpected shut down during startup, we need to obtain a fully configured instance using the appropriate Starter.
I had a similar symptom, the problem was solved for me by resolving the liveliness and readiness checks.
