Question

我是Scala开发人员，我在路由文件中收到此错误，如果我添加另一行给出的话，则 1008行 低于错误..

路线接受了多少行？我该如何解决这个问题？

Answer 1

通常，当没有足够的空间在Java堆中分配对象时，会抛出此错误。在这种情况下，垃圾收集器无法使空间可用于容纳新对象，并且无法进一步扩展堆。此外，当本机内存不足以支持加载Java类时，可能会抛出此错误。在极少数情况下，当花费过多的时间进行垃圾收集并且释放的内存很少时，可能会抛出LIMIT。

你基本上没有内存来顺利运行这个过程。想到的选项是：

使用java.lang.OutOfMemoryError环境变量指定更多内存，尝试介于两者之间的内容，例如 - JAVA_OPTS。
您也可以通过启用Xmx1G

有关GC调整的更多选项，请参阅Concurrent Mark Sweep

增加HEAP大小应该可以解决您的路线限制问题。

java.lang.OutOfMemoryError：Scala上超出了GC开销限制
