我已经开始面临本机内存分配问题了。我猜可能与-Xmx和-Xms设置有关。设置此值的推荐方法是什么?
目前我有:-Xmx13G -Xms6G
我读到建议设置相同的值,但没有解释为什么。
我得到的错误是:
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 746061824 bytes for committing reserved memory.
# Possible reasons:

我正试图在我的本地Ubuntu机器上安装elasticsearch,如下所示:
,当尝试运行'./elasticsearch‘时,得到以下错误:
Java HotSpot(TM) 64-Bit Server VM warning: INFO: <br>

我有一个运行Solaris 10的服务器,它报告70+ GiB空闲内存。我试图在64位模式下使用Java 1.7.0_80启动Tomcat 7.0.68。
服务器声称它无法分配717 MiB的内存。每次尝试时,我都会得到一个hs_err_pidxxx.log文件。它提出如下建议:
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 717225984 bytes for committ
我正在试用一个示例程序来了解泛型交换函数。
/*一个简单的泛型交换函数*/
#include<stdio.h>
#include<string.h>
void swap(void* xp,void* yp,int size){
//void temp = *xp; // we cant declare a variable as void , as we need to konw to de-reference as its not specifying any size info
// Hence used the smallest
我正在一个Java jar的Amazon实例上运行一些web应用程序,但是在12个小时左右之后,它总是会耗尽内存。下面是写入文件的错误消息:
