Capistrano deploys restart Sidekiq in an old release

[davidcelis]

I'm having an issue where a cap deploy (and the deploy:restart task it executes) is causing Sidekiq to restart in an old release. In fact, when I manually issue a cap sidekiq:stop and cap sidekiq:start, Sidekiq ends up starting in the oldest release rather than the current one. Here's what's happening:

I end up seeing a background job failure reported by New Relic, with a stacktrace pointing to:

/home/goodbrews/api/releases/20130530024501/app/workers/webhook_worker.rb

Note that release number. However, when SSHing into the server, here's what the current release is:

goodbrews@goodbre.ws:~/api$ ls -lah
total 16K
drwxrwxr-x 4 goodbrews goodbrews 4.0K May 31 16:49 .

As you can see, Sidekiq jobs are apparently running on old code. This is after I issued a new deployment to fix my worker and hopefully solve the error. But Sidekiq restarted in what is actually the oldest kept release. I issued a cap sidekiq:stop and cap sidekiq:start manually with no luck. Errors are still streaming in and pointing to the oldest release.

Here's my deploy.rb file for reference:

I should perhaps also note that the jobs being run currently are retries. Is it possible that retries are, for some reason, run against the code they were initially queued from?

Is it possible you have an old sidekiq process still running and that's where the errors are coming from?

That's actually what I found out was going on. I was waiting for a retry to trigger to make sure it wouldn't error out again, and it seems to be fine now. Sorry!
