Description

On our Azure DevOps Server we have a pipeline, which executes some automated tests. Currently, there's a test, which always hangs. Here's our dotnet call:

C:\AzAgent\_work\_tool\dotnet\dotnet.exe test --logger trx --results-directory C:\AzAgent\_work\_temp C:\AzAgent\_work\42\b\Assembly1.Test.dll C:\AzAgent\_work\42\b\Assembly2.Test.dll C:\AzAgent\_work\42\b\Assembly3.Test.dll --filter TestCategory!=PerformanceMeasurement --settings C:\AzAgent\_work\42\b\.runsettings --blame-crash --blame-crash-dump-type full --blame-hang --blame-hang-dump-type full --blame-hang-timeout 60m --verbosity Normal

Expected behavior

Because we are using the options --blame-hang --blame-hang-dump-type full --blame-hang-timeout 60m we would expect a dump to be created in our TestResults directory. Unfortunately, there's just a Sequence.xml, but no dump file.

I found the following lines in the log:

The active test run was aborted. Reason: Test host process crashed
Data collector 'Blame' message: The specified inactivity time of 60 minutes has elapsed. Collecting hang dumps from testhost and its child processes.

While reading another issue posted here I noticed, they had another line in their log, which I couldn't find in my log:

Data collector 'Blame' message: Dumping 13360 - dotnet.

Here's our .runsettings:

<RunSettings>
  <RunConfiguration>
    <!-- Run tests parallel using all cores on the machine -->
    <MaxCpuCount>0</MaxCpuCount>
