I wrote about this in the bugs section for 5.40 version but I realized that the following bug appears in V7.1.1.0, too:
After running a template in Zenno for like 20 minutes, the threads start to hang up (stop working), the instance shows nothing (in the address bar I have "about:page", and not the link where the bot should be), no proxy activated (although, it should be) and a blank window. When activating the traces feature I get things like these:

*When I actually have something in traces files (like above), it is something around an "if" action that waits for page to load. But the thread hangs at that "if". The logic is OK (no loop...I checked it tens of times), Furthermore, as I've already written, the instance shows a blank page with no proxy activated, and no loading action (I have the green light in the left down corner, saying "Ready"). Here it is an example (c4e1605c-2c3f-4da2-8559-d33952411504 is the "if" from the a/m log, where the project stops):

Here it is how the instance is looking in all these situations:

So, this happens in both V5.40 and V7.1.1.1.0, with any kind of template, on Chrome browser, with both residential and data server proxies.
When this happens, the CPU goes to 100%. If I just terminate the threads in Zenno, I have to wait like forever for Zenno to actually kill the threads. If remove the project from Zenno and add it again, when I start it, it will start on just a few threads (like 8 from a total of 20). The best thing to do in this situation is to shut down Zenno and restart it. This way, it will work fine for like 20 minutes. then, the threads will start to hang up again. After an hour, I need to do the shut down and restart trick.
