When running MbUnit (3.4.14.0) tests via TeamCity (8.0.2 build 27482), I got the error:

[Error] A fatal exception occurred while running tests.  Possible causes include invalid test runner parameters and stack overflows.

In the previous test run some Back-End tests ran OK, but on the last stage, UI tests hung and I cancelled the TeamCity job.

Any ideas what can cause the error?

Thanks.

  • you have an `OutOfMemoryException` in there. can you check your memory usage on your build server? – wal Jul 21 '14 at 10:42
  • Memory usage is acceptable, 40%-50%. Can the problem be with my tests? – Stan Desyatnikov Jul 21 '14 at 11:57
  • are you consistently getting that OutOfMemoryException ? if yes then see what happens to the mem as you run the tests. – wal Jul 21 '14 at 12:18
  • Yes, consistently. I don't have many tests. The failure happens, I think, when the tests start running. I didn't see any memory issues during a test run. – Stan Desyatnikov Jul 21 '14 at 13:20
  • I can only suggest general information at this stage, eg comment out a group of tests until you figure out which one causes the problem. also, see if any of the test processes are hanging around that shouldnt be (mstest works like this, am not referring to teamcity) – wal Jul 21 '14 at 13:31

A colleague of mine advised to restart the TeamCity service on the build server. It helped.
