Description

After deploying a simple API Provider integration (just the todo api with a single implemented flow), it gets restarted every couple of minutes. The provided API itself works fine, except during the restart, when it’s completely unavailable.

This is the log when the integration restarts:

@asmigala good point!

turns out we have an option #4 (from @lburgazzoli) that uses a different Spring Boot management port in application.properties management.port=8081 let’s see if this works

[asmigala]

I personally would go with option 2 as it is a less intrusive solution in my eyes.

What happens when the OpenAPI specifies an operation at the /health path?
