java.lang.OutOfMemoryError: GC overhead limit exceeded on Scala

Question

我是 Scala 开发人员，我在包含 1008 行 的 Routes 文件中收到此错误，如果我添加另一行抛出以下错误..

路由中接受了多少行？我该如何解决？

Answer 1

通常，当 space 不足以在 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 space 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 class 时，可能会抛出此错误。在极少数情况下，当花费过多时间进行垃圾收集并且释放的内存很少时，可能会抛出 java.lang.OutOfMemoryError。

您基本上运行内存不足运行进程顺利进行。想到的选项是：

使用 JAVA_OPTS 环境变量指定更多内存，尝试介于两者之间的一些东西，例如 -Xmx1G.
您还可以通过启用 -XX:+UseConcMarkSweepGC

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由限制问题。
