I'm getting the following error message from /var/log/nginx/error.log:

2014/07/17 08:36:21 [alert] 8206#0: worker process 8207 exited on signal 11 (core dumped)
2014/07/17 08:36:21 [alert] 8206#0: worker process 8210 exited on signal 11 (core dumped)

2014/07/17 08:36:26 [alert] 8206#0: worker process 8209 exited on signal 11 (core dumped)

2014/07/17 08:36:26 [alert] 8206#0: worker process 8236 exited on signal 11 (core dumped)

/var/log/nginx/access.log shows the redirect to https which happens if you visit the http address:

[17/Jul/2014:09:22:54 +0000] "GET / HTTP/1.1" 301 185 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_5) AppleWebKit/537.76.4 (KHTML, like Gecko) Version/6.1.4 Safari/537.76.4"

Any ideas what could be causing this? It is on Ubuntu 12.04 and a standard apt-get install nginx.

This is the config:

server {
    listen      80;
    server_name domain.com;
    rewrite     ^ https://$server_name$request_uri? permanent;
}

server {
    listen                  443 ssl;
    server_name             domain.com;
    ssl_certificate         /ssl/path.crt;
    ssl_certificate_key     /ssl/path.key;
    error_page              404             /404.html;
    error_page              500 502 503 504 /50x.html;
    location                = 50x.html {
        root    /usr/share/nginx/html;
    }
    location                / {
        root    /project/path/root;
    }
    access_log              /project/path/logs/nginx-access.log;
    error_log               /project/path/logs/nginx-error.log;
    client_max_body_size    20m;
}

I only get this error when I view the site using Safari, it happens on multiple machines not just mine and it's the same error displayed on each Safari.

This could be related to the ssl session cache issue that is described in this ticket for nginx, http://trac.nginx.org/nginx/ticket/235.

Workaround is to use the same session cache for all server blocks, e.g. to configure it on the http{} level.
