我有一个Java程序可以在具有2GB物理内存和2GB交换的Solaris 10 X86上运行 .
该程序在Linux 64位运行良好，它只消耗大约450MB内存 .
但是当它在Solaris中运行时，它总是报告OutOfMemoryError，并且我注意到在错误发生之前，它试图使用> 4GB的虚拟内存，这在32位系统上绝对不可能 .
那么为什么JVM会尝试使用那么多虚拟内存呢？有没有办法告诉JVM不要使用那么多的虚拟内存？
谢谢 .

感谢大家的意见！这是完整的错误消息：
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 32756 bytes for ChunkPool::allocate
# 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)
