log doesn't work in production with delayed job

I\'m suffering some weird issue where my delayed_jobs are failing in production. Finally I narrowed it down to the logger. If I comment out my log function calls, everythi

Answer 1

I've had a similar issue. The logging in the collectiveidea fork is being rewritten - see this issue for more info. Perhaps try the newest version to see if that fixes it for you.

Answer 2

It looks like you're trying to log to a closed file. Have you perhaps considered trying the SyslogLogger gem?

Here's an article on how to use it with rails, which should help get you started.

Woody Peterson found the problem here: http://groups.google.com/group/delayed_job/browse_thread/thread/f7d0534bb6c7c83f/37b4e8ed7bfaba42

The problem is:

DJ is using Rails' buffered log in production, and flushing the buffer is not being triggered for some reason (don't know if it's flushed by buffer size or explicitly flushed after a request).

The temporary fix (credit to Nathan Phelps) is:

When in production the buffered log is set to an auto_flushing value of 1000 which means that flush is not called until 1000 messages have been logged. Assuming you're using collectiveidea's fork of delayed_job, you can address this by setting auto_flushing to a more reasonable value in command.rb right after the logger is initialized on line 64. I.E.

Delayed::Worker.logger = Rails.logger

Delayed::Worker.logger.auto_flushing = 1 # or whatever

Works for me perfectly!
