HikariCP too many Connections with jooq due to that Hikari Cp Pool Initialisation Fail - jooq

Question

I have service which is built in spring boot (2.4.5v) and its integrated with and jooq. When we perform the load in our service we are getting too many connection with Jooq.
I am using the DSL context like this.
public class CourseRepository {
#Autowired private DSLContext dslContext;
}
And I haven't provide explicit bean of DSLContext.
and Hikari CP configuration look like this,
spring.datasource.url=[My RDS URL]
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jooq.sql-dialect=MySQL
spring.datasource.type=com.zaxxer.hikari.HikariDataSource
spring.datasource.hikari.pool-name=[DB Name]
spring.datasource.hikari.initial-size=5
spring.datasource.hikari.maximum-pool-size=40
spring.datasource.hikari.minimum-idle=2
spring.datasource.hikari.idle-timeout=10000
spring.datasource.timeout=10000

Another Error
error.class:org.springframework.dao.DataAccessResourceFailureException
error.message:jOOQ; SQL [Query]; Too many connections; nested exception is java.sql.SQLNonTransientConnectionException: Too many connections
After reading several links and post, I found we have to provide the DSLContext bean,
#Primary
#Bean(name = "dslContext")
public DSLContext dslContext(#Qualifier("dataSource") DataSource dataSource) {
this.dataSource = dataSource;
log.info("Datasource {}", dataSource);
org.jooq.Configuration config = new DefaultConfiguration();
config.set(dataSource);
config.set(SQLDialect.MYSQL);
return DSL.using(config);
}
After adding these configuration ], I am getting different error.
