dotCover & Typemock - unable to complete cover session: [JetBrains dotCover] Coverage session finished with errors: PDB server error: Too large table index


since we added typemock 8.8 to one of our solutions, I cannot longer run dotCover as it fails repeatedly with the following error:

Test Run Failed.

[JetBrains dotCover] Analyzed application exited with code '1'

Command line used:

"C:\Program Files (x86)\Typemock\Isolator\8.8\BuildScripts\TMockRunner.exe" "C:\Development\dotcover\dotCover.exe" analyse /ReportType=HTML /Output="%CD%\xxx.html" "/TargetExecutable=%VSINSTALLDIR%\Common7\IDE\CommonExtensions\Microsoft\TestWindow\vstest.console.exe" /TargetWorkingDir=. "/TargetArguments=xxx.Test\bin\Debug\xxx.Test.dll"

The testcontainer has about 100 tests - so not massive.


Any ideas?

Thanks, Tom


Hello Tom,

It looks like PDB files were erroneously generated and didn't pass our check. Does rebuild of the project help with the issue?  Would it be possible to send us the problem solution for deeper investigation or reproduce the same issue in a sample one? You can attach it here or with a new issue on our bug tracker.


Hi Olga,

I tried re-building a few times and it did not help. I cannot pass the solution on to you, its a bigger project of my company. Is there anything else I could supply in order to help your investigation?

Thx! Tom
