求教 Springboot 连接 MongoDB，偶尔会出现 Operation timed out (Read failed)如何解决？

如题。微服务项目中使用 JPA 操作 MongoDB

SpringBoot 配置如下

spring.data.mongodb.option.min-connection-per-host=5
spring.data.mongodb.option.max-connection-per-host=100
spring.data.mongodb.option.threads-allowed-to-block-for-connection-multiplier=5
spring.data.mongodb.option.server-selection-timeout=30000
spring.data.mongodb.option.max-wait-time=120000
spring.data.mongodb.option.max-connection-idle-time=0
spring.data.mongodb.option.max-connection-life-time=0
spring.data.mongodb.option.connect-timeout=10000
spring.data.mongodb.option.socket-timeout=0

spring.data.mongodb.option.socket-keep-alive=true
spring.data.mongodb.option.ssl-enabled=false
spring.data.mongodb.option.ssl-invalid-host-name-allowed=false
spring.data.mongodb.option.always-use-m-beans=false

spring.data.mongodb.option.heartbeat-socket-timeout=20000
spring.data.mongodb.option.heartbeat-connect-timeout=20000
spring.data.mongodb.option.min-heartbeat-frequency=500
spring.data.mongodb.option.heartbeat-frequency=10000
spring.data.mongodb.option.local-threshold=15

这配置应该没什么问题吧？但是偶尔查询就会失败。有时候连接也会失败。问题出现的不频繁，不知道原因，没法稳定复现。
