Broken pipe error in Cloud Integration

[#1]

Since the start of June we are seeing failed messages for our integration with error: javax.servlet.ServletException: Error during write of the response: , cause: java.io.IOException: error 32 - Broken pipe.

Though the messages failed in Cloud Integration we can confirmed that the file was delivered to the webservice endpoint successfully. This issue is recurring though there are cases of the same integration flow executions that were successful in Cloud Integration. So the issue is intermittent. Last update of the integration package happens on May 13 so we have no idea what is causing this error. Just to give more context on the integration flow, the integration flow is called via Integration Center as REST API URL and is triggered via an event in ISC (Intelligent Service Center) in SF. We tried replicating it in our internal system but we cannot replicate the same issue reported by our customers.

Hi maik.offerle thank you for your response. Sorry for the delay in my feedback. See screenshot of what we have in Integration Center monitor which corresponds to the message in Cloud Integration which completed successfully.

Here's the screenshot of the one that triggers a failed message in Cloud Integration. Based on the time stamp it is taking 3 minutes+ before the http error is raised.

This is what you can see in Cloud Integration where the soap call executed successfully but the iflow failed because of that error read time out:

Any suggestion on how we can resolve this? This is working fine since 2019 and we just had this issue late 3rd week of May this year. Thanks!
