延遲招聘工人試圖連接只讀從動件

Question

下面是從日誌文件中實際的錯誤：

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! 
2013-02-20T20:56:03+00:00 app[worker.1]: PG::Error: ERROR: cannot execute UPDATE in a read-only transaction 
2013-02-20T20:56:03+00:00 app[worker.1]: : UPDATE "delayed_jobs" SET locked_at = '2013-02-20 20:56:02.982379', locked_by = 'host:05c659a5-86fd-46dd-b139-263e49a96171 pid:2' WHERE id IN (SELECT id FROM "delayed_jobs" WHERE ((run_at <= '2013-02-20 20:56:02.882553' AND (locked_at IS NULL OR locked_at < '2013-02-20 16:56:02.882574') OR locked_by = 'host:05c659a5-86fd-46dd-b139-263e49a96171 pid:2') AND failed_at IS NULL) ORDER BY priority ASC, run_at ASC LIMIT 1 FOR UPDATE) RETURNING * 

此錯誤也出現在追隨者日誌。這就是爲什麼假設有一個問題。延遲工作版本：3.0.5

看來，問題來了最新的更新。詳情請參見本Github的問題： https://github.com/collectiveidea/delayed_job_active_record/issues/34

對我來說，降級到0.3.3工作。
