Cause
This issue occurs because you install the .NET Framework 4.5 in your BizTalk Server environment, and it is not officially supported prior to Cumulative Update 7 (CU7) for BizTalk Server 2010. You have to use the .NET Framework 4.0 when you run BizTalk Server 2010 Cumulative Update 6 (CU6) or earlier.
Resolution

Cumulative update information

This issue was first fixed in the following cumulative update of BizTalk Server:
Status
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
Workaround
To work around the issue, turn off XLANG AppDomain Shutdown by following steps:
  1. Locate to your BizTalk Server folder. By default, it is C:\Program Files (x86)\Microsoft BizTalk Server 2013.
  2. Save a copy of the BTSNTSvc64.exe.config file by using a new name.

    Note Save a copy of the BTSNTSvc.exe.config file if it is a 32-bit host. You can check the error message to see whether the crash occurs to BTSNTSvc.exe or BTSNTSvc64.exe.
  3. Open the original file in notepad and locate the <configuration> node. Then, directly below it, add the following:
    <configSections>
    <section name="xlangs" type="Microsoft.XLANGs.BizTalk.CrossProcess.XmlSerializationConfigurationSectionHandler, Microsoft.XLANGs.BizTalk.CrossProcess" />
    </configSections>
  4. Locate to the </runtime> node, and add the following:
    <xlangs>
    <Configuration>
    <AppDomains AssembliesPerDomain="50">
    <DefaultSpec SecondsIdleBeforeShutdown="-1" SecondsEmptyBeforeShutdown="-1"/>
    </AppDomains>
    </Configuration>
    </xlangs>
  5. Recycle the host.

More information
Starting with CU7, BizTalk Server 2010 supports both .NET Framework 4.0 and 4.5.x for the runtime. CU7 can be installed either prior to or after you install the .NET Framework 4.5.x.
