I think I am still having this problem in LoadUI Pro 2.6.2
I am using a SoapUI Runner with ~100 threads. When I had two Table Logs attached to the runner, the UI would freeze after 60-80 seconds. This happened every time, 100% reproducible.
As soon as I removed both of the Table Logs then I could run the test indefinitely.
Was this problem supposed to have been fixed in version 2.6? According to this page:
