postgresql – Heroku Postgres：此连接已关闭

我开发了一个小型的Heroku Grails Postreg应用程序.部署后20分钟它会工作正常,之后我总是得到：

This connection has been closed.. Stacktrace follows: Heroku/myapp
- org.postgresql.util.PsqlException: This connection has been closed. Heroku/myapp

我已经通过将其添加到DataSource.groovy来解决它：

dataSource {
    pooled = true
    properties {
       maxActive = -1
       minEvictableIdleTimeMillis=1800000
       timeBetweenEvictionRunsMillis=1800000
       numTestsPerEvictionRun=3
       testOnBorrow=true
       testWhileIdle=true
       testOnReturn=true
       validationQuery="SELECT 1"
    }
}
