CFD Online Discussion Forums - why Starccm+ ran out of memory on Centos7

When I ran Starccm+ simulation on Centos7. Memory can easily explode， however, physical memory is about 128G. The log file is as follow:
Code:
#

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

# Native memory allocation (mmap) failed to map 12288 bytes for committing reserved memory.

# Possible reasons:

#   The system is out of physical RAM or swap space

#   The process is running with CompressedOops enabled, and the Java Heap may be blocking the growth of the native heap

# Possible solutions:

#   Reduce memory load on the system

#   Increase physical memory or swap space

#   Check if swap backing store is full

#   Decrease Java heap size (-Xmx/-Xms)

#   Decrease number of Java threads

#   Decrease Java thread stack sizes (-Xss)

#   Set larger code cache with -XX:ReservedCodeCacheSize=

#   JVM is running with Unscaled Compressed Oops mode in which the Java heap is

#     placed in the first 4GB address space. The Java Heap base address is the

#     maximum limit for the native heap growth. Please use -XX:HeapBaseMinAddress

#     to set the Java Heap base and to place the Java Heap above 4GB virtual address.
