我试图在RHEL7系统上运行CassandraV3.11.3。但是在尝试启动Cassandra的时候却面临着记忆错误。
面临以下错误：

OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x0000000080000000, 1073741824, 0) failed; error='Cannot allocate memory' (errno=12)

# 

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

# Native memory allocation (mmap) failed to map 1073741824 bytes for committing reserved memory.

# An error report file with more information is saved as:

# /../../../hs_err_pid16347.log

hs\u err\u pid16347.log文件

# 

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

# Native memory allocation (mmap) failed to map 1073741824 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=

# This output file may be truncated or incomplete.

# 

# Out of Memory Error (os_linux.cpp:2760), pid=16347, tid=0x00007f7a61dec700

# JRE version:  (8.0_212-b04) (build )

# Java VM: OpenJDK 64-Bit Server VM (25.212-b04 mixed mode linux-amd64 compressed oops)

是否检查了“free-m”并且有足够的内存可用，但是这个错误仍然与内存有关，这可能与什么有关？这里定义的-xmn1g。
考虑到足够的可用内存，尝试检查“ulimit-a”，并按照此链接建议进行更新https://serverfault.com/questions/662992/java-on-linux-insufficient-memory-even-though-there-is-plenty-of-available-memor 重新启动系统，并试图再次启动Cassandra，但仍然面临同样的问题。系统级是否有其他需要更新的设置？
还有谁能分享cassdandra 3.11和操作系统兼容性矩阵？
