I am very interesting in an answer on this issue, as I seem to run into massive memory leaks in TC when running my MainScript.
I can run my test cases individually all day long and there are no problems, but on two different PCs we encounter 'Out of memory' errors in TC when running the MainScript (calling all test scripts), as TC eventually eats up 1,7Gb of RAM and our system runs out of memory.
I run my MainScript at night when I leave the office, and the next morning everything hangs and I got hundreds of those error messages in TC. All I can do is kill TC process in Task Manager.
We are currently using v7.52.
