Hi Willy, We are seeing a strange problem on the patched server. We have several haproxy servers running but only one with the latest patch, and this haproxy has frozen twice in last two days, basically it hits max open connections 2000 on frontend and then stalls. From the logs it has 1999 connections on one of the backends which is nginx, but nginx_status shows me only a few active connections. It only happens on the patched haproxy server and does not happen anywhere else. Interesting thing is this haproxy is not the one doing SSL, we have two haproxies on the same box with the latest binary, the SSL one seems ok but the non SSL one keeps on accumulating connections.
Right now, I see connections building on one backend hitting 150 in the last few hours, but the backend nginx only shows about 20 active connections.
