免责声明：本文为 VMRC connections drops across WAN in vRA 7.1 and later (2148652) 的翻译版本。尽管我们会不断努力为本文提供最佳翻译版本，但本地化的内容可能会过时。有关最新内容，请参见英文版本。

无法从 vRealize Automation 使用 VMware Remote Console 访问远程 WAN 位置中的虚拟机。

在 catalina.out 日志文件中，您会看到类似以下内容的条目：

vcac: [component="cafe:console-proxy" priority="WARN" thread="consoleproxy" tenant] com.vmware.consoleproxy.async.EventDispatcher.handleOperation:209 - [CP] The selection key sun.nio.ch.SelectionKeyImpl@3cd819bb has been invoked a critical number of times.Closing

从桌面向 vRealize Automation 设备执行 Ping 操作的结果为：

25 packets transmitted, 25 packets received, 0.0% packet loss
Round-trip time min/avg/max/stddev = 0.371/0.485/0.627/0.058 ms

从 vRealize Automation 设备向远程 vSphere 执行 Ping 操作的结果为：

24 packets transmitted, 24 received, 0% packet loss, time 23005ms
Round trip time min/avg/max/mdev = 228.877/230.275/252.392/4.683 ms

Purpose

将 consoleproxy.connection.criticalcount=500 属性添加到 security.properties 文件可解决此问题。<?xml:namespace prefix = “o” />

Cause

如果 CRITICAL_COUNT 参数达到限制（默认值为 100）而导致连接赶不上传输的数据包，则会出现此问题。

Resolution

要解决此问题，请在 security.properties 文件中添加 consoleproxy.connection.criticalcount=500 属性。

生成 vRealize Automation 虚拟设备的快照。

以 root 用户身份登录到 vRealize Automation 虚拟设备节点。

运行以下命令停止 vcac-server 服务：

service vcac-server stop

使用文本编辑器打开文件 /etc/vcac/security.properties。

添加属性：

consoleproxy.connection.criticalcount=500

注意：编辑之前请备份此文件。

运行以下命令，启动 vcac-server 服务：

service vcac-server start

等待服务启动，打开 /var/log/vmware/vcac/catalina.out 文件并找到消息“CRITICAL_COUNT set to”。它显示了当前严重计数，并验证是否选取了您设置的值。

注意：CRITICAL_COUNT 字段显示每秒事件可标记为 ready 的最大次数。
