chanti vlad commented on JENKINS-9104:
--------------------------------------

"Jenkins mustn't kill mspdbsrv.exe to be able to build more than one Visual 
Studio project at the same time."

Although i will try the indicated workaround, i think this would be good to 
have it as a feature somewhere, maybe in the node configuration?
                
> Visual studio builds started by Jenkins fail with "Fatal error C1090" because 
> mspdbsrv.exe gets killed

>             Project: Jenkins
>          Issue Type: Bug
>          Components: core
>    Affects Versions: current
>         Environment: Windows XP, using MSBuild or devenv.exe to build MS 
> Visual Studio Projects
>            Reporter: Christoph VogtlÃĪnder
>            Priority: Minor

> I run into errors when using a customized build system which uses Visual 
> Studio's devenv.exe under the hood to compile VisualStudio 2005 projects 
> (with VC++ compiler). When starting two parallel builds with Jenkins (on 
> different code base) the second job will always fail with "Fatal error C1090: 
> PDB API call failed, error code '23' : '(" in exactly the same second the 
> first job finishes processing. Running both jobs outside Jenkins does not 
> produce the error.
> This has also been reported for builds executed by MSBuild on the Jenkins 
> user mailing list [1].
> I analysed this issue thoroughly and can track the problem down to the usage 
> of mspdbsrv.exe. This program is automatically spawned when building a 
> VisualStudio project. All Visual Studio instances normally share one common 
> pdb-server which shutdown itself after a idle period (standard is 10 
> minutes). "It ensures access to .pdb files is properly serialized in parallel 
> builds when multiple instances of the compiler try to access the same .pdb 
> file" [2].
> I assume that Jenkins does a clean up of its build environment when a 
> automatically started job finishes (like as described at 
> http://wiki.jenkins-ci.org/display/JENKINS/Aborting+a+build). I checked 
> mspbsrv.exe with ProcessExplorer and the process indeed has a variable 
> JENKINS_COOKIE/HUDSON_COOKIE set in its environment if started through 
> Jenkins. Killing mspdbsrv.exe while projects are still connected will break 
> compilation. 
> Jenkins mustn't kill mspdbsrv.exe to be able to build more than one Visual 
> Studio project at the same time.
