Ignite 客户端从 2.7.0 升级到 2.9.0 后不稳定
Ignite client unstable since upgrade from 2.7.0 to 2.9.0
我们在我们的应用程序中升级了一堆库，其中一个是 ignite。现在客户端模式下的 ignite 运行 正在崩溃。我的想法是，其中一项升级导致缓存的大小增加。 （所以我认为ignite的升级不是问题）。
所以我将堆大小从 10 GB 增加到 20 GB。但是当使用了大约 50% 时，JVM 挂起。
我很困惑为什么它在只有 50% 的使用率时会这样做。

检查您是否能够从客户端计算机连接到服务器计算机，并且防火墙配置是否正确设置。
参见：https://ignite.apache.org/docs/latest/clustering/network-configuration
确保您已设置：Djava.net.preferIPv4Stack=true 如果您使用的是 IPv4 地址。
如果涉及容器 and/or 个私有地址，可能会导致连接问题。
