I have a Java program to run on Solaris 10 X86 with 2GB physical memory and 2GB swap.
The program runs fine in Linux 64-bit, it consumes only about 450MB memory.
However when it runs in Solaris, it always reports OutOfMemoryError, and I noticed that right before the error happens, it was trying to use > 4GB of virtual memory, which is definitely not possible on 32-bit system.
So why does JVM tries to use that much virtual memory? Is there a way to tell JVM not to use that much virtual memory?
Thank you.
Edit:
Thanks for everyone's opinions! Here is the complete error message:
#
# 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

# 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)
