我们在 couchbase 的集群中有 2 个节点，它们之间共享 4 个存储桶，当我们尝试使用 JAVA api 在存储桶中插入数据时，会出现以下错误：-

`

它显示“预计接收数据的节点处于非活动状态”当它启动并运行时......我们应该更改每个存储桶的 RAM 配额（现在非常高）还是我们应该减少要插入的数据还是防火墙问题？？

这很可能是防火墙问题。您似乎无法连接到 Couchbase，并且您的 Couchbase 集群中的内存配额或数据量不应导致缓慢。尝试从客户端所在的同一台机器上通过 telnet 连接到 Couchbase 端口 11211。如果您无法 telnet 到那台机器，那么这将是防火墙问题的强烈迹象。

telnet <ip address> 11211
