ZP "Active tab of instance is not found"

[bfirstpl]

Hello

I saw few discussions about this kind of problem. I saw that in one of previous versions this bug was fixed but I get this error in ZP 5.1.0.0. in more than one of my projects.
Yesterday I started a project to parse Google results. 5 threads. After 40 minuss of stable running all threads stopped and in Logs I saw this message "active tab of instance...". I starded project again and after 1 hour I saw the same message.

Can you tell me what is going wrong? How to fix it? I can not work with this problem.

It happens when you use infinite loops. If you use looops in order for your template to work for hours you have to use action Browser - Restart instance from time to time. Other wise it will fail sooner or later.
