单声道：太多堆路段增加MAXHINCR或MAX_HEAP_SECTS当应用程序在内存占用超过4 GB [英] Mono: Too many heap sections Increase MAXHINCR or MAX_HEAP_SECTS when app takes more than 4 GB in memory

问题描述

我运行我的单应用程序在bitnami linux与8 GB的内存。它是一个复杂的文件合并应用程序，它应该需要大量的RAM，因为它的工作原理。
但每次它需要超过4 GB的RAM，它崩溃，并显示以下错误信息：

I am running my mono application at a bitnami linux with 8 GB of memory. It is a sophisticated file merger application, which is supposed to take a lot of RAM as it works. But every time it takes more than 4 GB of RAM, it crashes with following error message:

Too many heap sections: Increase MAXHINCR or MAX_HEAP_SECTS

Debug info from gdb:


=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================

Aborted

这里是mono -V的输出：

Here's the output of mono -V :

Mono JIT compiler version 2.8.2 (tarball Tue Aug 30 18:06:04 UTC 2011)

能够在单声道上运行内存密集型应用程序吗？

What should I do to be able to run memory-intensive apps on mono?

* UPDATE
我为32位系统编译和编译应用程序。因此，这个错误。

*UPDATE I screw up and compiled the app for 32 bit systems. Hence, this error.

推荐答案

我的理解是，这个错误来自于Boehm GC。

My understanding is that this error stems from the Boehm GC.

请先尝试此操作。使用下面的脚本从源代码下载和构建。在脚本的configure部分进行此更改：

Try this first. Download and build from source using the script below. In the configure part of the script, make this change:

./ configure --with-large-heap = yes

./configure --with-large-heap=yes

除了要设置的其他任何配置问题之外，还要执行此操作。这应该设置LARGE_CONFIG标志。

Do this in addition to whatever other config issues you want to set. This should set the LARGE_CONFIG flag.

如果你想手动设置它（我不知道为什么），这里是步骤：

If you wanted to set it manually (I don't know why), here are the steps:

1. 下载单声道来源并在此处运行脚本

http：//www.integratedwebsystems .com / 2011/08 / install-mono-2-10-3-on-ubuntu-using-bash-script /

1. 现在返回并在
顶部添加以下代码：

1. Now go back and add the following code to the top of

build / mono-2.10.8 / libgc / include / gc_config_macros.h

build/mono-2.10.8/libgc/include/gc_config_macros.h

#ifndef LARGE_CONFIG
#define LARGE_CONFIG
#endif

1. 现在开始构建/ mono-2.10.8并运行

make
sudo make install

make sudo make install

希望这将编译一个新的单声道解决你的问题。生成的mono将在/ opt

Hopefully this will compile a new mono that solves your problem. The resulting mono will be in /opt

一些最受影响的代码在libgc / include / private / gc_priv.h中，但是维护者很好地把条件对于LARGE_CONFIG标志，因此最好使用它。

Some of the most affected code is in libgc/include/private/gc_priv.h, but the maintainers have nicely put conditionals all over for the LARGE_CONFIG flag, so it's probably best to work with that.
