Rails app hosted on heroku: Error R12 (Exit timeout)
问题 I have a Rails 3.1.4 app hosted on heroku. I have added the logentries add-on. I didn't touch the default configuration for alerts, and I now receive every few hours an alert: 'Exit timeout': Exit timeout: Heroku/myappname 2012-03-23 11:01:41.723 168 <40>1 2012-03-23T11:01:41+00:00 d. heroku web.1 - - Error R12 (Exit timeout) -> Process failed to exit within 10 seconds of SIGTERM You are receiving this email because your Logentries alarm "Exit timeout" has been triggered.
