爲什麼在Beanstalkd隊列作業失敗 - Laravel 4.2

Question

我有「隨機」有些工作我beanstalked隊列失敗。 兩個問題：

1 /通過查看數據庫失敗的作業表哪能interprate裏面是什麼記錄？數據關閉意味着在讀取原始數據時「沒有」。有什麼需要做更多的信息？

2 /我通過Laravel的控制檯日誌去了，這就是失敗：

[2015-04-29 15:40:51] production.ERROR: exception 'ErrorException' with message 'Trying to get property of non-object' in /home/forge/api.hello.me/vendor/jeremeamia/SuperClosure/src/Jeremeamia/SuperClosure/SerializableClosure.php(99) : eval()'d code:6 
Stack trace:... 

但我不知道究竟是什麼失敗...堆棧跟蹤不幫助，只是開始於

[internal function]: Jeremeamia\SuperClosure\SerializableClosure::{closure}(Object(Illuminate\Queue\Jobs\BeanstalkdJob)) 
#2 /home/forge/api.hello.me/vendor/jeremeamia/SuperClosure/src/Jeremeamia/SuperClosure/SerializableClosure.php(64): ReflectionFunction->invokeArgs(Array) 

，完成了幾行後在

#15 /home/forge/api.hello.me/vendor/symfony/console/Symfony/Component/Console/Application.php(124): Symfony\Component\Console\Application->doRun(Object(Symfony\Component\Console\Input\ArgvInput), Object(Symfony\Component\Console\Output\ConsoleOutput)) 
    #16 /home/forge/api.hello.me/artisan(59): Symfony\Component\Console\Application->run() 
    #17 {main} [] [] 

我如何能理解任何想法/找到OU發生了什麼？隊列甚至沒有失敗所有的時間...

PS：全堆棧跟蹤：

方式Laravel隊列工作是序列化所有你提供的​​的數據，它堅持認爲在你的數據庫中。當您處理隊列中，它會奇蹟般地反序列化所有這些數據，這樣你已經基本上在內存中，當你彈出它放入隊列也做了同樣的對象。 當你改變一個序列化對象的類定義，或者你的對象沒有完全正確地序列化時（這似乎是這裏的情況），問題就出現了......

我建議你不要序列化匿名函數，因爲Laravel使用SuperClosure來做到這一點，而且它非常黑。

[internal function]: Jeremeamia\SuperClosure\SerializableClosure::{closure}(Object(Illuminate\Queue\Jobs\BeanstalkdJob))

嘗試推簡單的對象到你的魔豆隊列（即不發送對象隊列），你不會有這個問題。
