| After upgrading from Jenkins 2.204.2 to 2.222.1, our builds started failing non-deterministically when trying to download artifacts.
It seems that Jenkins no longer honors the "--httpKeepAliveTimeout=60000" switch.
I confirmed that Jenkins is running with switch.
Yet a download with a slow consumer will fail with a partial download. (for testing: "curl -f -u $jenkins_auth $artifact_url | (sleep 6; wc -c)" On the server side, the log indicates that the command-line switch was ineffective and the default 5s timeout is still in use:

The default 5s timeout is short enough that a simple "curl | tar xf" sometimes trips it when unpacking many small files on an overloaded VM. Please consider changing the default back to jetty's 30s. |
