I have spring boot application which runs on the cloud and i use mongo db.

When i check the logs i see that sometimes i got the the socketException.

Here is the logs

In my local machine I couldn't reproduce this exception.

Does anyone have any idea why I got this exception ?

    It shows MongoDB health check failed. You probably want to verify the health of your cluster. If this is a replica set are all nodes up and available? What does rs.status() show? Commented Aug 19, 2021 at 17:56

    You can check if the tcp connections to the clusters are active or not. Commented Aug 19, 2021 at 18:05

Caused by: java.net.SocketException: Broken pipe (Write failed) would imply that that the Java machine tried to write to the network, but the socket was not (possibly no longer?) in a state that could be written.

Check for basic networking problems. If you don't find any try decreasing the TCP keepalive timeout.

If that doesn't work, catch the exception and retry whatever operation this was.
