Hi @hansen, thanks for your reply.

I followed the recommendations at your stackoverflow link and changed
config.considerallrequestslocal to true
but found that
config.loglevel
was already set to the recommended
:debug

I ran service unicorn restart after making these changes and found still that there was no unicorn.log changes.

To be perfectly clear, I renamed my existing, not changed for two weeks unicorn.log file to ol.unicorn.log.old, and after restarting unicorn, there is no new unicorn.log being generated. I don’t know why.

Here is my nginx server block:

server {
    listen   80;
    root /home/rails/popEFX/public;
    server_name _;
    index index.htm index.html;

    location / {
            try_files $uri/index.html $uri.html $uri @app;
    }

    location ~* ^.+\.(jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|mp3|flv|mpeg|avi)$ {
                    try_files $uri @app;
            }

     location @app {
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_redirect off;
            proxy_pass http://app_server;
    }
}

Okay, thought I was getting somewhere.

I did some hunting around and found the correct log file under myproject/log/unicorn.log. Found this most recent logging there:

...

So I ran ‘bundle update rack’, verified that rack was listed among the gems, and restarted unicorn and reloaded nginx. I rechecked unicorn.log and found that unicorn still errors out on rack-01.6.8 despite it being listed among my gems on completion of bundle update.

So I am continuing to figure out what needs doing to prevent this.

Third update:

after running a rake tmp:cache:clear, then bundle update, then bundle install, unicorn is now choking on the Gem

i18n-0.8.4

Which is listed among my gems after bundle install. The cache clear, update, install actions don’t have any impact on this problem. Unicorn just keeps choking on the gem, crashing, and respawning.

I also tried ‘bundle clean –force’ before the cache clear/update/install to no avail.
