Java 内存模型 Java 程序内存运行分析 Java 内存管理建议 JVM 内存溢出和参数调优  当遇到 OutOfMemoryError 时该如何做？ ▶ 常见的 OOM（Out Of Memory）内存溢出异常，就是堆内 存空间不足以存放新对象实例时导致。 ▶ 永久区内存溢出相对少见，一般是由于需要加载海量的 Class 数据，超过了非堆内存的容量导致。 ▶ 栈内存也会溢出，但是更加少见。 Java 内存模型 Java 程序内存运行分析 Java 内存管理建议 JVM 内存溢出和参数调优  当遇到 OutOfMemoryError 时该如何做？ ▶ 常见的 OOM（Out Of Memory）内存溢出异常，就是堆内 存空间不足以存放新对象实例时导致。 ▶ 永久区内存溢出相对少见，一般是由于需要加载海量的 Class 数据，超过了非堆内存的容量导致。 ▶ 栈内存也会溢出，但是更加少见。 Java 内存模型 Java 程序内存运行分析 Java 内存管理建议 JVM 内存溢出和参数调优  当遇到 OutOfMemoryError 时该如何做？ ▶ 常见的 OOM（Out Of Memory）内存溢出异常，就是堆内 存空间不足以存放新对象实例时导致。 ▶ 永久区内存溢出相对少见，一般是由于需要加载海量的 Class 数据，超过了非堆内存的容量导致。 ▶ 栈内存也会溢出，但是更加少见。

Setup Your Project Edit Your Project Assets, Files, & Data System Introduction Blender File Data-Blocks Custom Properties Linked Libraries Asset Libraries Media Formats Importing & Exporting Files Add-ons application, Blender runs on Linux, macOS, as well as Windows systems. It also has relatively small memory and drive requirements compared to other 3D creation suites. Its interface uses OpenGL to provide sculpting and improved workflow, and reworked library handling to manage missing and deleted data-blocks. 2.78 – September 2016: Cycles support for spherical stereo images for VR, Grease Pencil works

New Modules mod_proxy_fcgi FastCGI Protocol backend request body as a response via the output filter stack. mod_slotmem_shm Provides a Slot-based shared memory provider (ala the scoreboard). mod_xml2enc Formerly a third-party module, this supports internationalisation objects, based on the previous implementation of the mod_ssl session cache. Providers using a shared-memory cyclic buffer, disk-based dbm files, and a memcache distributed cache are currently supported. Cache
