Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

写入核心转储失败。核心转储已被禁用。要启用核心转储，请在再次启动Java之前尝试“ulimit -c unlimited”

ulimit -c unlimited 设置core文件大小为不限制大小

三种解决办法

1. 修改服务器的最大可开文件数、最大进程数（无效）

vi /etc/security/limits.conf

网络上文章很多
3. 升级JDK8至JDK10（有效）
升级和重载的步骤基本一致
