Hello all, I have a strange behavior when using upstream/keepalive and it could be fine if someone can give me some feedback regarding this setup.
I have multiple locations with proxy_pass directive, i use proxy_http_version 1.1 and "Connection" header is cleared. In the upstream block, i have 2 or more upstream IP and i have add the directive keepalive. Now, sometimes i see this error log : "upstream prematurely closed connection while reading response header from upstream". A tcpdump show that nginx send a GET to his upstream but the TCP connection is closed and nginx don't receive the response from upstream. Most of the time, nginx uses another upstream server and the transaction is successfully completed. This behavior appears with different upstream server. If someone has experiencing this kind of issue, feedback are welcome !
