Issue: Katalon freezes while running test cases until process killed
Katalon 5.10.1 on Windows 64-bit
We have tests with hundreds of steps, which are contained in subprocesses and methods. All of our test cases are in test suites, but even executing a test suite with 10 tests causes Katalon to freeze, sometimes after the first test, sometimes a little later. The test suite will continue to run in the background and even generate a report, but Katalon never becomes responsive again and has to be killed.
We tried changing the log levels, but it has not helped. At this point, Katalon freezes several times a day and the rest of the team has not updated from older versions.
Primary log file error (repeated many times, but only most recent pasted here):
