Hello, it looks like this patch triggers some issues with ack processing (possible previously, but now more probable): see details in suggested patch. I'm also attaching bad.log and good.log. The first one demonstrates that nginx is not sending any ACKs since it is switched into idle mode and the window is not increasing. Since the client code is symmetric, deadlock occurs. _______________________________________________ nginx-devel mailing list nginx-devel@nginx.org https://mailman.nginx.org/mailman/listinfo/nginx-devel
