Question

我正在尝试在运行CentOS 5.7的Linux服务器上运行激活器ui。我安装了Java和激活器，但每当我运行“activator ui”时，我都会遇到以下错误：

[ERROR] [09/15/2014 15:42:22.431] [default-akka.actor.default-dispatcher-2] [ActorSystem(default)] Uncaught error from thread [default-akka.actor.default-dispatcher-2] shutting down JVM since 'akka.jvm-exit-on-fatal-error' is enabled

这只是服务器没有足够内存的问题，因为当我运行“cat / proc / meminfo”时，它应该足够了。

Answer 1

服务器是否有交换？如果没有，那么添加它可能会省你。 Activator产生了几个JVM，它们都很大，因为JVM只是很大。你需要一些空间。在各个JVM上调低-Xmx可能会有所帮助，但只有在应用程序无法运行之前它才会变得如此之低。
