Cassandra添加节点问题，失败；错误='无法分配内存'（errno = 12）
问题描述 投票：0回答：1
我有一个带14个节点的cassandra（v3.11.4）集群，我想添加一个新节点。机器具有256GB内存，并且我将堆大小（最大和最小）设置为64GB。但是由于内存错误，我无法添加新节点！确切的问题是什么，我需要做什么？
日志的最后一行如下：

错误消息表明JVM无法提交内存，因为mmap syscall返回了错误代码12（ENOMEM）。
[通常在进程达到操作系统内存限制之一时发生：
内存映射数超过
vm.max_map_countsysctl限制。对于Cassandra，这是一个非常常见的问题，因为Cassandra倾向于映射成千上万个文件，并且默认限制相当低-大约65K。如何检查：
vm.max_map_count，其中wc -l /proc/<pid>/maps是Java进程ID。如何解决：
<pid>进程的虚拟内存总量超过
sudo sysctl vm.max_map_count=1000000如何检查：
RLIMIT_AS，RLIMIT_AS如何解决：在同一外壳中启动Cassandra之前的
ulimit -v。[
cat /proc/<pid>/status被禁用，并且过量使用率太低。如何检查：
ulimit -v unlimited，Overcommit，sysctl vm.overcommit_memory如何解决：
sysctl vm.overcommit_ratio
