    If you use English to communicate, more people will be able to help you.

    I have a script that scans information from more than 500 websites and runs continuously without stopping. I usually run 25 threads, but after a day, I often have to restart the software because it seems like there are not enough threads running. It's possible that some websites or scripts encounter errors, leading to thread interruptions. Is there a way to ensure that there are always 25 threads running, and that websites with errors will be retried in the subsequent loops?

    Why did you duplicate your first message to me in this topic? It was in English anyway.

    My script need to change the threads number dynamically, e.g.: 9:00-10:00 i need 30 threads,10:00-11:00 40 threads ...
    What should I do？

    Dynamically increase the number of threads can not. Specify at once the maximum number of threads, and let the excess threads sleep. Or use the action "Call function in several threads".

    Is this correct usage of linesfromfile, labels and threads?

    @caplaz

    Is that the correct method?

    Yes, this will work.

    Can I write to the csv file?

    Yes, there is action called Write File(which also has append switch).

    Can also use csv_generate api for proper escaping.

    Action "Custom" and

    [[CSV_LINE]] = csv_generate(["a","b","c"],",")

    Or should that be done in a seperate file?

    Better use database, not csv

    I want my threads to loop forever but no matter what I do they eventually end. Sometimes with success and sometimes with error.

    If you have any failure during thread run, for eaxmple failed to load with proxy error, the thread will end. And as long as you set "use each line one time" to resource, it won't be used again.

    Ending with success is strange, probably, because you are using labels inside loops, 20 version has good explanation about this:

    There are two types of goto: long and short. Short move is performed if goto and label are located inside same block (has one parent). This type of move preserves execution history and script continues afterward. In other cases long move is performed, which clears execution history. Long move case is perfect if you are jumping on script start, but if you move inside loop, you must use another move to leave it, otherwise thread will stop with success message.

    Anyway, if you have some code, that may return error, just wrap it inside ignore errors action.
    You can also wrap whole list of actions that you want to do with account inside ignore errors block.
