为什么在Beanstalkd队列作业失败 - Laravel 4.2

Question

我有“随机”有些工作我beanstalked队列失败。 两个问题：

1 /通过查看数据库失败的作业表哪能interprate里面是什么记录？数据关闭意味着在读取原始数据时“没有”。有什么需要做更多的信息？

2 /我通过Laravel的控制台日志去了，这就是失败：

[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么失败...堆栈跟踪不帮助，只是开始于

[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) 

，完成了几行后在

#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发生了什么？队列甚至没有失败所有的时间...

PS：全堆栈跟踪：

方式Laravel队列工作是序列化所有你提供的​​的数据，它坚持认为在你的数据库中。当您处理队列中，它会奇迹般地反序列化所有这些数据，这样你已经基本上在内存中，当你弹出它放入队列也做了同样的对象。 当你改变一个序列化对象的类定义，或者你的对象没有完全正确地序列化时（这似乎是这里的情况），问题就出现了......

我建议你不要序列化匿名函数，因为Laravel使用SuperClosure来做到这一点，而且它非常黑。

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

尝试推简单的对象到你的魔豆队列（即不发送对象队列），你不会有这个问题。
