Broken pipe error in logs

twilkinson

I'm seeing the same issue described in this old post, which unfortunately offers no further explanation or solution:

I'm running FusionAuth version 1.47.1 in a docker container.
The system seems to be behaving properly, but from time to time this error shows up in the logs:

Has there been a resolution for this?

@twilkinson That message is logged when an HTTP client closes a connection before FusionAuth can fully send a response. This could be as innocuous as a user closing their browser before a page has completed loading.

Some thoughts:

Do you see other exceptions in the log?
Possibly related to database connections? What does the load look like on the DB?
Do you see any issues on Elastic if you are using it?
