在近期的系统巡检检查中，发现一个最近新安装上线的EXADATA一体机环境的数据库后台ALERT日志中有报错ORA-00603: ORACLE server session terminated by fatal error ORA-27515: inadequate memlock limit or driver settings；初看起来是进程异常关闭，检查发现数据库未宕机，查看TRACE为普通的用户进程而不是数据库后台进程，业务使用正常。

报错日志如下：

继续分析此报错，结合ORACLE MOS文档 EXADATA : ORA-00603 AND ORA-27515 during EXAChk run with Autonomous Health Framework (AHF) 20.1.1. (Doc ID 2662144.1)、Instance crashes with ORA-00603, ORA-27515 (Doc ID 2700814.1)等文档，初步判断是AHF工具BUG导致。至于解决方式，官方给出的是升级AHF打补丁或者关闭AHF，我这里使用了最简单的关闭方式，步骤命令如下：（root用户下执行，2个计算节点都执行）

#exachk -autostop

#tfactl stop

MOS中描述如下：
