Our problem was that unicorn master process wasn't restarted correctly, because it was killed with:

/bin/kill -s HUP `cat tmp/pids/unicorn.pid`

Which doesn't actually kill the unicorn master process (only reloads the config, see SIGHUP documentation). Verify by running ps -ef | grep 'unicorn'.

Our problem was solved changing the killing of unicorn master process with:

/bin/kill `cat tmp/pids/unicorn.pid`

PS: cat tmp/pids/unicorn.pid just outputs the PID of the unicorn master process.
