启用自动防兰索保护功能后、可能会发生控制器中断

适用场景

• ONTAP 9
• 自主的兰索姆软件保护
• 反勒索软件监控
• 内存泄漏 

问题描述

• 启用反勒索软件监控后、  控制器可能会发生类似于以下内容的崩溃重新启动：

• 在涉及大量文件创建和删除以及/或数TB的高熵数据操作的工作负载中、  如果一个或多个卷的反勒索软件监控 处于"已启用"状态、则可能会发生内存泄漏问题描述
• 如果卷处于反勒索软件监控 学习(演练)、暂停或禁用状态、则不会发生此内存泄漏
• 当反勒索软件监控 尝试检测潜在的勒索软件模式时、少量内存会被泄露
• 一段时间内泄漏的总内存量可能导致系统崩溃、并显示崩溃字符串"Process mgwd Unresponed for xxx seconds"
