ApacheIgnite:“；已检测到阻塞的系统关键线程”；分区交换器中的异常

我有一个由6个节点组成的ApacheIgnite集群。偶尔，在运行几个小时后，日志中会记录一些如下所示的异常，节点会停止。我不在受影响的服务中使用事件处理程序或发布/订阅处理程序。是什么导致了这些异常？这是否意味着这些错误消息中总是提到“分区交换器”线程

我在Kubernetes管理的Linux容器上使用ApacheIgnite for.NETV2.7。谢谢大家!

建议升级到2.7.5，因为它显示的伪错误更少

否则，文档部分将介绍如何对其进行优化：

我们遇到了相同的错误，我们只使用了2.7.5版。非常感谢您的帮助。目前还没有，但我确实解决了原来的问题——谢谢@你能分享一下你的解决方案吗？我在新环境中遇到过同样的问题，在Ignite上没有任何工作负载，我不明白出了什么问题。我们遇到了同样的错误，我们只在版本2.7.5中。你把这个修好了吗？非常感谢您的帮助。
