Gallio error when tests are run via TeamCity: "Possible causes include invalid test runner parameters and stack overflows"

Question

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.
Gallio.Model.ModelException: An exception occurred while invoking a test driver.

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.

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