jrockit jdk 异常：

Attempting to allocate 40G bytes

There is insufficient native memory for the Java

Runtime Environment to continue.

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)

  Disable compressed references (-XXcompressedRefs=fals
