I had nginx 0.6.32 and just upgraded to 0.7.61 and still have the same
memleak issue.
What happens is as soon as I start nginx, it starts using ram and
continues to use more and more and more over a 16 hour period is
consumes 8gb ram and all the swap and then errors out because it cant
use any more.
This never used to happen until recently and the only difference at all
in the config is more server entries.

here's the config:

user www www;

worker_processes 16;
error_log logs/error.log;
worker_rlimit_nofile 65000;

events
{

worker_connections 40000;
}

proxy_redirect default;

}
}
server

ssl on;

proxy_pass https://3.4.5.6;
proxy_redirect https://3.4.5.6/

proxy_redirect default;
proxy_set_header Host
$host; ##Forwards host along
proxy_set_header X-Real-IP
$remote_addr; ##Sends realip to customer svr
proxy_set_header X-Forwarded-For
$remote_addr; ##Sends realip to customer svr
proxy_set_header X-FORWARDED_PROTO https;
}
}

And these server entries repeated about 60 or so times and that's it.
When it was around 40 we never had a memleak issue.

This is on Linux, kernel is 2.6.25

Thanks
