Mongo Health Indicator is showing UncategorizedMongoDbException

[abecedarius]

Hi team,

We have used the custom MongoConfiguration by extending the AbstractMongoConfiguration in our application. We have configured the below properties.

We have used Spring Boot 2.0.1.RELEASE, Spring data Mongo 2.0.6.RELEASE

mongo.connection.timeout=2000
mongo.socket.timeout=5000
mongo.server.selection.time=2000
mongo.max.connection.per.host=100
mongo.client.thread.allowed=4
mongo.max.wait.time=2000
mongo.connection.uri=mongodb://localhost:27017/testDB?serverSelectionTimeoutMS=2000&connectTimeoutMS=2000&maxIdleTimeMS=15000&maxLifeTimeMS=600000
mongo.db.name=testDB
mongo.client.read.concern=LOCAL
mongo.client.write.concern=1
mongo.client.write.timeout=5000
mongo.write.concern.journal=true
mongo.write.timeout.unit=MILLISECONDS
mongo.client.read.preference=PRIMARY
cache.expire.time=3600000

But getting the below exception for the mongo health check monitor.
Not sure what may be causing this:

org.springframework.boot.actuate.mongo.MongoHealthIndicator:89 - MongoDB health check failed

Not able to find out what may be causing this exception. Please suggest how to resolve this.

That's not a general issue/discussion forum for Spring Boot/Spring Data MongoDB issues.

Looking at the exception, it's caused by MongoSocketWriteException which indicates an underlying I/O problem such as a non-responsive MongoDB server. If this problem persists, post a question on StackOverflow long with the full stack trace. The one here is truncated.
