<br>
This is what I see in the nginx error log:<br>

When this happens I see this in the uwsgi error log:<br>
<br>

<br>
Note the weird timestamps. The first uwsgi message is more then 2<br>
minutes after the nginx message. And the second uwsgi message has a<br>
timestamp before the previous uwsgi message. What's up with that??<br>
<br>
Here is my nginx config:<br>
<br>
worker_processes 1;<br>
<br>
events {<br>
worker_connections 1024;<br>
}<br>
<br>
http {<br>
include mime.types;<br>
default_type application/octet-stream;<br>
keepalive_timeout 65;<br>
sendfile on;<br>
<br>
# set client body size to 20M<br>
client_max_body_size 20M;<br>
<br>
include /etc/nginx/sites-enabled/*;<br>
}<br>
<br>
<br>
and here is my local site file:<br>
<br>
# motor_nginx.conf<br>
<br>
# the upstream component nginx needs to connect to<br>
upstream django {<br>
server unix:///usr/local/motor/motor.<wbr>sock; # for a file socket<br>
}<br>
<br>
# configuration of the server<br>

# the port your site will be served on<br>

<br>

proxy_connect_timeout 600;<br>
proxy_send_timeout 600;<br>

<br>
# Django media<br>
location /media {<br>
alias /usr/local/motor/motor/media;<br>
}<br>
<br>
location /static {<br>
alias /usr/local/motor/motor/static;<br>
}<br>
<br>
# Finally, send all non-media requests to the Django server.<br>
location / {<br>
uwsgi_pass django;<br>
include /usr/local/motor/motor/uwsgi_<wbr>params;<br>
}<br>
}<br>
<br>
How can I debug or fix this?<br>
<br>
Thanks!<br>
