LGHT0001 : Exception of type 'System.OutOfMemoryException' was thrown

[eaiacc]

I'm trying to create a bundle for my installer. The bundle contains among other thing an msi package of a third-party product. In addition to msi file, this package includes a directory structure with about 11000 files. The directory structure must be stored in the same directory as the msi file at the moment of installation.

MsiPackage element looks like:
    <MsiPackage Id="3rd.Client" DisplayName="3rd-party product" SourceFile=".\3rd\Client_32.msi" Compressed="yes" >
      <PayloadGroupRef Id="3rd.Client.Payload" />
    </MsiPackage>

PayloadGroup element looks like (I've generated it with PowerShell):
        <PayloadGroup Id="3rd.Client.Payload ">
          <Payload SourceFile="<Payload-Directory>\<File-1>" Name="<Target-Directory>\<File-1>" />
          <Payload SourceFile="<Payload-Directory>\<File-2>" Name="<Target-Directory>\<File-2>" />
    .....
If I'm trying to build the project in Visual Studio, light.exe is running for >20 minutes and then crashes with LGHT0001: Exception of type 'System.OutOfMemoryException' was thrown

Is my approach correct from conceptual point of view? What else could I do?

Thanks in advance!
