UCCE Outbound Dialer失败与WinDump进程

Introduction

本文描述遇到的一个问题，当WinDump进程与Cisco Unified Contact Center Enterprise (UCCE)时Outbound Dialer一起使用。

Prerequisites

Requirements

Cisco 建议您了解以下主题：

• Cisco UCCE
  
• Cisco UCCE版本8.x会话初始化协议(SIP)或小型客户机控制协议(SCCP)拨号程序

Components Used

本文的信息根据Cisco Unified Contact Center Enterprise (UCCE) Outbound Dialer。

The information in this document was created from the devices in a specific lab environment.All of the devices used in this document started with a cleared (default) configuration.If your network is live, make sure that you understand the potential impact of any command.

问题

当Outbound Dialer进程日志查看时，您注意到WinDump进程失败每15秒：

-------------
13:00:12:615 dialer-baDialer Trace: WinDump process has crashed, restarting... 
13:00:12:617 dialer-baDialer Trace: CreateProcess succeeded with szCmdline = windump -I 1
-tt -C 20 -s 0 -W 20 -w DialerCapture udp port 58800 
dwProcessId= 262600 hProcess = 256784
13:00:28:843 dialer-baDialer Trace: WinDump process has crashed, restarting... 
13:00:28:844 dialer-baDialer Trace: CreateProcess succeeded with szCmdline = windump -I 1

dwProcessId= 262412 hProcess = 256792
13:00:45:069 dialer-baDialer Trace: WinDump process has crashed, restarting...

当WinDump重复时失败，导致导致Outbound Dialer服务失败的存储器泄漏情况。

解决方案

有也许导致此问题的两三个方案：

• 没有正确地设置捕获选项Outbound Dialer注册密匙。连接对\ HKEY_LOCAL_MACHINE \软件\ Cisco Systems， Inc. \ ICM \ <customer实例> \拨号程序并且切记捕获选项注册密匙设置为- i 1 - tt - C 20 - s 0 - W 20 - w DialerCapture。
  
  在某些状况下，注册密匙设置为- I 1 - tt - C 20 - s 0 - W 20 - w DialerCapture，导致失败。当Outbound Dialer从一个更早版本时，被升级这经常被看到。 欲了解更详细的信息，请参见Cisco Bug ID CSCuh16754 (WinDump进程在拨号程序失败)。
• Wireshark软件也许影响被捕获的动态地连接程序库文件(DLL)。如果Wireshark在服务器上安装为了排除故障和以后被卸载， WinPcap删除由卸载可能导致此问题。Wireshark卸载进程去除获取DLL wpcap.dll和packet.dll， WinDump需要。

为了确认需要的文件存在，并且WinDump适当地运作，请完成这些步骤：

1. 确定wpcap.dll和Packet.dllfiles是存在这些位置：
   • C:\Windows\SysWOW64
   • C:\Windows\System32
   如果没找到DLL文件，请与Cisco技术支持中心(TAC)联系为了得到DLL文件的适当的版本。
2. 为了确认正确地安装WinDump进程并且正确地获取数据，请检查这些命令的输出：

   C:\>windump -V
   windump version 3.9.5, based on tcpdump version 3.9.5
   WinPcap version 4.1.2 (packet.dll version 4.1.0.2001), based on libpcap version 1.0 branch
   1_0_rel0b (20091008)
