前段时间在做一个项目时遇到一个问题，主要是由于bizTalk为了提高处理速度，采用的是多线程进行处理，默认是2个，原来的接收程序没有考虑多线程，产生了一些问题，后来经过咨询发现biztalk的并发线程数量是可以配置的，根据具体境况设置合适的数值。

2,在结束标签</configuration>之前加上如下配置信息

<configuration>

…

   <system.net>

      <connectionManagement>

         <add address= "*" maxconnection = "20"/>

      </connectionManagement>

   </system.net>

</configuration>

3,重启BizTalk服务

BTSNTSvc.exe.config文件的全部内容如下：

<?xml version="1.0" ?>
<configuration>
    <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <probing privatePath="BizTalk Assemblies;Developer Tools;Tracking;Tracking\interop" />
        </assemblyBinding>
    </runtime>
    
    <system.runtime.remoting>
    
        <channelSinkProviders>
            <serverProviders>
                <provider id="sspi" type="Microsoft.BizTalk.XLANGs.BTXEngine.SecurityServerChannelSinkProvider,Microsoft.XLANGs.BizTalk.Engine" securityPackage="ntlm" authenticationLevel="packetPrivacy" />
            </serverProviders>
        </channelSinkProviders>
    
        <application>
            <channels>
                <channel ref="tcp" port="0" name="">
                    <serverProviders>
                        <provider ref="sspi" />
                        <formatter ref="binary" typeFilterLevel="Full"/>
                    </serverProviders>
                </channel>
            </channels>
        </application>
    </system.runtime.remoting>

   <system.net>

      <connectionManagement>

         <add address= "*" maxconnection = "20"/>

      </connectionManagement>

   </system.net>
</configuration>
