Related to support ticket 00502942: dptf_helper.exe process has crashed
When processes unrelated to the application under test crash, they cause the test run to fail. In my case the dptf_helper.exe (related to the Intel dynamic thermal framework was crashing every few days), and had nothing to do with my test run, other than it made the test run fail. Trying various ways to work around this crash as suggested by the Smartbear support team did not work and I ended up having to remove the .exe file from TestComplete which monitors for application crashes.
