从延迟作业运行时,我经常遇到堆栈级别太深的错误。
我在延迟作业中的很多地方都遇到了类似的错误,但是当我在控制台中逐行运行相同的代码时,它工作正常....

代码太多,无法包含在本论坛中。
所以我要明确的问题是:
1.)经过研究我怀疑我只是没有足够的堆栈空间。我看到我可以使用 ulimit 来提高它,但我不知道如何将此 ulimit 用于延迟作业,我在我的 shell (.bashrc) 中提高了 ulimit 但这似乎没有帮助。谁能确认我的堆栈空间不足以及如何修复? (这是我得到这个想法的地方:http://dalibornasevic.com/posts/5-ruby-stack-level-too-deep-systemstackerror)
2.) 如果它不是 ulimit,它可能是什么,我该如何调试它....我在这个堆栈中没有看到任何递归或循环。
