Application gets RSTs on outgoing TCP sessions.

[t4lz]

Bug Description

The application gets resets which lead to a ECONNRESET.
I couldn't locate the cause neither in the layer's nor in the agent's logs, so I think maybe the RSTs originate with the layer (the layer drops the connection early and a RST is sent to the app on the mirror stream).

Steps to Reproduce

It only reproduced on the CI, and only in twice out of thousands of outgoing requests.
Triggering the CI on this request #553 is almost guaranteed to lead to an error at some point, but you would probably have to try it a couple of times until you get this specific error (or change it in some way to keep running the test after one try has failed, like a simple way would be to duplicate the e2e job, so you get 1 error per job.)
