Spring boot Spring Data Neo4j:无法在配置的最长时间内从池中获取连接

我正在对我的Neo4j客户端进行压力测试，该客户端是使用spring-boot-starter-data-Neo4j构建的

经过一段时间后，应用程序抛出错误无法获取任何请求的连接

这是我的Neo4j连接的bean配置。有人能检查并告诉我们可以做什么吗

id("org.springframework.boot") version "2.4.0"



@Configuration
    @EnableTransactionManagement
    class Neo4jConfig(
        @Value("\${spring.neo4j.uri}")
        val neo4jDBUri: String,

        @Value("\${spring.neo4j.authentication.username}")
        val neo4jDbUserName: String,

        @Value("\${spring.neo4j.authentication.password}")
        val neo4jDbUserPassword: String
    ) : AbstractNeo4jConfig() {
//        https://medium.com/neo4j/try-and-then-retry-there-can-be-failure-30bf336383da
        @Bean
        override fun driver(): Driver {
            val config: Config = Config.builder()
                .withMaxTransactionRetryTime(60, TimeUnit.SECONDS)
                .withLeakedSessionsLogging()

                .withMaxConnectionPoolSize(100)
                .build()

            return GraphDatabase
                .driver(neo4jDBUri, AuthTokens.basic(neo4jDbUserName, neo4jDbUserPassword), config)
        }
    }

    fun reactiveTransactionManager(

    ): ReactiveTransactionManager = ReactiveNeo4jTransactionManager(driver, databaseNameProvider)

    }
