Hi all, I’m seeing a massive spike of nginx connections in read state, which appears to be related to fastcgi upstream connections [1]. Usually I’ll have 0.6 avg and ~25 max connections in read state, but with 0.8.15/0.7.62 I’ve seen 34.0 avg and 52.4 max… and it looks like my fastcgi upstream doesn’t like that very much. 😉 Thoughts? Thanks, - Jeff [1] I reverted to proxy\_pass and the read state connections disappeared. ---

The read state is just reading request (not including body). This state is before any fastcgi interaction. ---

Here’s what the connections in read state chart looks like: [http://www.gnome.org/~jdub/2009/nginx-0.7.62-connread.png](http://www.gnome.org/~jdub/2009/nginx-0.7.62-connread.png) There _could_ be a slight lagging correlation with the active connections chart, showing spikes of connections left in the read state about a minute after similar spikes in active connections… but it’s definitely not a one-to-one relationship, even excluding the static files being served. - Jeff ---

Many reading states may indicate some network issues.
