hi @ld0906 - the error originates in Node.js itself because it's rejecting an invalid HTTP response header from the server. More information here: nodejs/node#27711

It's quite odd that it's not 100% reproducible. Do you only see it under load? What's the stack of the system under test? (server, web framework etc)
