.NET 4.5已然到来,预览了解了下Large Object Heap在.NET 4.5中的效能改进.借此和大家来探讨下.本文不讨论Loder Heap,SOH(samll object heap),LOH(large object heap),JIT Heap,Process Heap关系和区别.也不会着重讨论GC,单论Large Object Heap在.NET 4.5中的改进. 在比较频繁使用Large Object(对象不小于85,000bytes)系统中,经常容易抛出Out-of-m…

原文地址:https://www.simple-talk.com/dotnet/.net-framework/the-dangers-of-the-large-object-heap/ You'd have thought that memory leaks were a thing of the past now that we use .NET. True, but we can still hit problems. We can, for example, prevent memory…

关于LOH(Large Object Heap)的. .NET CLR中对于大于85000字节的内存既不像引用类型那样分配到普通堆上,也不像值类型那样分配到栈上,而是分配到了一个特殊的称为LOH的内部堆上,这部分的内存只有在GC执行完全回收,也就是回收二代内存的时候才会回收.因此,考虑如下情形: 假设你的程序每次都要分配一个大型对象(大于85000字节),但却很少分配小对象,导致2代垃圾回收从不执行,即使这些大对象不再被引用,依然得不到释放,最终导致内存泄漏. 作者:Ziheng链接:https…

报错信息: Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. 解决方法: 在catalina.bat中增加如下设置 set JAVA_OPTS=-server -XX:MaxHeapSize=256m -Xms512m -Xmx512m…

问题:打开eclips启动tomcat发现报出Could not reserve enough space for object heap错误. 解决办法:1.首先检查tomcat是否能正常启动.remove掉tomcat里所有的项目启动.如果仍然有错就说明是tomcat有问题.删除tomcat 重新部署一个,即可解决.    2.如果启动tomcat没错,项目添加后有问题,就是jvm 溢出  内存不够.就要进行修改jvm内存启动即可.…

ionic build Android后的报错问题 ionic 升级了splashscreen和statusbar的插件后,执行ionic build android会一直报打包错误.原因是过低的Android-platform版本不支持新的 splashscreen和statusbar插件 解决 办法是:  ionic platform add android@6.1.2      添加Android平台前加上版本号就行 然而,又有了新的问题:Error occurred during ini…

Error occurred during initialization of VM Could not reserve enough space for object heap Java虚拟机(JVM)分配的内存大于系统可用内存数,所以没有足够的空间分配给JVM来创建Object 解决方法:可以看看机器的系统内存目前还剩下多少,保证足够启动Java时设定的-Xmx512M -Xms512M -XX:MaxPermSize=256M 如Eclipse: 为JVM设置合适的参数(比目前的要小) (…
