服务调用mongodb，Exception receiving message 请看堆栈信息

Question

问题描述：mongdb版本是3.4，其实没有做什么，就普通的查询，写入，因为是测试阶段，qps很小。

1. 这个异常是怎么产生的，需要做什么配置或者调整？

问题已经困扰了2天，没有找到具体原因。求助@Mongoing中文社区
请看堆栈信息

请问问题解决了吗

Answer 2

这个问题困扰了我多天，现已解决；
一开始我以为设置了mongodb.socketKeepAlive=true就可以解决，但是还是会遇到closed的连接；
关于keepalive，Mongo官方的说明：
On Linux, mongod and mongos processes limit the keepalive to a maximum of 300 seconds (5 minutes) on their own sockets by overriding keepalive values greater than 5 minutes.
也就是说，Linux上的mongod进程会关闭5分钟无操作的连接；详见：https://docs.mongodb.com/manu...
因为Client在默认情况下并不会主动回收这些连接；
解决办法：设置 Max connection idle time，因为Client在默认情况下并不会主动回收这些连接，连接池中某个连接的空闲时间超过该值，将丢弃该连接并重新新建立一个连接，配置如下：
mongodb.max-connection-idle-time=60000
