Question

下面是从日志文件中实际的错误：

2013-02-20T20:56:03+00:00 app[worker.1]: SQL (11.1ms) UPDATE "delayed_jobs" SET locked_by = null, locked_at = null WHERE (locked_by = 'host:05c659a5-86fd-46dd-b139-263e49a96171 pid:2') 
2013-02-20T20:56:03+00:00 app[worker.1]: rake aborted!

此错误也出现在追随者日志。这就是为什么假设有一个问题。延迟工作版本：3.0.5

看来，问题来了最新的更新。详情请参见本Github的问题： https://github.com/collectiveidea/delayed_job_active_record/issues/34

对我来说，降级到0.3.3工作。
