在阿里云服务器上安装jdk7+tomcat7环境,启动tomcat,不发布任何应用,jvm也会不停出错
每隔一个小时就生成一个hs_err_pid*.log

系统版本:
Linux iZ23usxuuqdZ 2.6.32-431.23.3.el6.x86_64 #1 SMP Thu Jul 31 17:20:51 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

hs_err_pid*.log内容如下:

#

There is insufficient memory for the Java Runtime Environment to continue.

pthread_getattr_np

Possible reasons:

The system is out of physical RAM or swap space

In 32 bit mode, the process size limit was hit

Possible solutions:

Reduce memory load on the system

Increase physical memory or swap space

Check if swap backing store is full

Use 64 bit Java on a 64 bit OS

Decrease Java heap size (-Xmx/-Xms)

Decrease number of Java threads

Decrease Java thread stack sizes (-Xss)

Set larger code cache with -XX:ReservedCodeCacheSize=

This output file may be truncated or incomplete.

看起来是内存不够了。要不加内存，要不设置定时重启tomcat(不推荐).
