我目前正在一个项目中工作，这个项目涉及到一个raspberry pi集群上的分布式ApacheIgniteDB。我想有两个独立的数据区域，其中一个启用了持久性。这是我的自定义配置：

<beans xmlns="http://www.springframework.org/schema/beans"

            </bean>
        </property>
    </bean>
</property>

</bean>

我用基于官方dockerfile的自定义conf构建了自己的docker映像，只是用以下内容更改了基本映像： FROM arm32v7/openjdk:8-jre-alpine 麻烦开始于我试图开始我的形象。。。我有一些警告，例如：

Nodes started on local machine require more than 80% of physical RAM what can lead to significant slowdown due to swapping (please decrease JVM heap size, data region size or checkpoint buffer size) [required=1300MB, available=924MB]

还有几个错误，比如：

[SEVERE][tcp-disco-msg-worker-[crd]-#2-#46][G] Blocked system-critical thread has been detected. This can lead to cluster-wide undefined behaviour [workerName=disco-notifier-worker, threadName=disco-notifier-worker-#45, blockedFor=11s]

在那之后，我不可能激活集群（通过rest或control.sh脚本）并查询它。
如果有人有一个配置文件的rpi工作我真的很感兴趣！
编辑：
我尝试了@alamar的建议（-xmx384和检查点页缓冲区大小20m），但激活时仍然有以下错误：

这里有几件事。
首先，我认为你不需要更新docker文件。pi3有64位内核，因此默认值应该可以工作。我创建了这个，它在pi4上运行良好。
其次，在jvm和数据区域之间，分配的内存比pi的内存多：
在本地计算机上启动的节点需要80%以上的物理ram，这可能会由于交换而导致显著减速（请减小jvm堆大小、数据区域大小或检查点缓冲区大小）[必需=1300mb，可用=924mb]
你看起来只有150mb的堆外内存，所以我想知道你的java堆有多大？8gb应该足够了。
如果您的pi正在交换到磁盘，这可能会导致阻塞的系统线程。
最后，由于启用了身份验证，因此在尝试激活集群时需要提供用户名和密码。默认设置为ignite/ignite。

人们偶尔会在rpi上启动它。
在您的情况下，请尝试减小jvm的xmx（-xmx384可以），并显式指定持久区域的检查点页缓冲区大小（在您的情况下，20m应该可以）。
如果您仍然看到“线程阻塞”异常，请共享完整的日志。您可以使用ApacheIgnite用户列表。另外，请描述当你尝试激活时会发生什么。
