3个以上的ajax调用是否会产生500个内部服务器错误

Question

我有一个函数，我将在其中调用每个ajax调用的9函数。在localhost中没有错误，在我的网站上我发现了这个问题。

第3次功能完成后。其他6人获得500内部服务器错误。所以我试图移动另外6个函数将其置于工作的函数内（例如：getBoardLabelCard（id）还有3个函数 - ＆gt; getStartDate（id），getDueDate（id），getChecklist（id））并且它正在工作。 多个ajax调用中是否有任何代码模式，或者我应该在一个函数中执行所有ajax？

感谢您提供任何建议。对我来说真的很有帮助。
