Windows 2019 上堆外持久性存储的 Apache Ignite OOM 错误

问题描述

在Windows 2019 64 位 上启动Ignite 时，我们遇到OOM 错误。我们正在使用 48GB 的堆外存储。当我们将堆外大小减少到 30 GB 时，它工作正常。我们正在使用本机持久性。持久化位置是默认的。我检查了安装 Ignite 的磁盘空间，它有超过 100 GB 的可用空间。

点燃版本：2.8.1

java 版本“1.8.0_281” Java(TM) SE 运行时环境（构建 1.8.0_281-b25） Java HotSpot(TM) 64 位服务器 VM（构建 25.281-b25，混合模式）

Windows 版本：2019 64 位，RAM 128 GB，我们尝试安装的可用磁盘空间为 100 GB

Ignite 正在其他节点上工作。即使在具有相同配置的其他 Windows 2019、2012 机器上。

点燃配置

        </property>
        <!-- set the size of wal segments to 512 MB -->
        <!-- the default 64 MB Could not store large single position entry and caused error-->
        <property name="walSegmentSize" value="#{512 * 1024 * 1024}"/>
        <!-- Keep WALs Separately  -->
        <property name="walPath" value="D:\am-bmt-ignite-wal\wal"/>
        <property name="walarchivePath" value="D:\am-bmt-ignite-wal\archive"/>
    </bean>
</property>

是否有任何与 Windows Box 相关的配置可以检查？

我在 Ignite 组中看到了类似的问题： http://apache-ignite-users.70518.x6.nabble.com/After-increasing-maxsize-in-DataRegionConfiguration-Ignite-throws-out-of-memory-exception-td30907.html

如果有人遇到过这种问题，请告诉我。
