Spring Hazelcast嵌入式缓存打印过多日志（目标是此节点！->；[10.1.8.58]：5701，“堆栈跟踪”：“d3566be0>；j.l.IllegalArgumentException…”

我有一个带有spring security 5的spring boot 2.5应用程序，其中我使用嵌入式hazelcast缓存来支持spring会话。这个应用程序部署在openshift上，有两个吊舱，其中运行着相同的应用程序，因此我使用hazelcast kubernetes插件进行服务发现。一切正常。但是，我可以看到应用程序日志中充斥着下面的日志行。 有什么建议hazelcast配置有什么问题吗？为什么会生成这么多日志行？

10.1.8.58是后来加入集群的第二个pod的IP地址，日志仅在该pod中打印

您得到的异常

SplitBrainMergeValidationOp

意味着Hazelcast集群可能已经在splitbrain中启动，然后尝试合并到一个集群中。你能检查一下你是否遵守了所有的规定吗

---

特别是，检查是否使用StatefulSet（而不是部署）。在DNS查找发现的情况下，使用部署可能会导致Hazelcast以裂脑模式启动。

谢谢。事实上，这个问题和我们使用DNS查找发现部署的建议是一样的。但是，如果我们希望使用DNS环上发现部署，如何解决此问题？有什么建议吗？请尝试增加

服务dns超时
