When log import fails in a normally executed test

The test log may be written successfully for the first trial, but it may not be written normally for the further trials, which leads to failing a test that previously executed successfully.

unable open to file : ...\targetResult.log

The reason for this problem is that the previously executed log writing process (eclipsec.exe) did not exit normally.
To resolve the problem, force quit eclipsec.exe in the task manager or reboot the target.
