Hello,
I am getting several thread_flags and thread_handler  as in below:



what does it means by them and what could be the reason to generate all of these flags?

Thanks,
Elsayed

They are automatically generated by UR when they are running threads, if you have threads in your program they have an ID and a handler so that UR can interact with them.  Generally, I just ignore them.  If you really want to understand more about how UR does things you can download the `programName`.script file from your robot, or a simulator, and use notepad or something like that to open it and read it.  Its very helpful for really understanding what is happening under the covers with the program.  Polyscope is just a fancy User Interface that lays on top of the actual script file that gets generated and executed.  When you press play on the program a compiler generates the script file and that is what is actually sent to the controller for execution. 

Thank you Sir I just I thought I did something not normal for that reason the thread start throwing theses handlers.
Thanks,
