You must kill them off and start new ones when the code they are running (including anything called in other script modules) changes. Not only is your failure to kill these off preventing them from calling your updated code, but they are leaking huge gobs of gateway heap memory. (This is true of async threads no matter what kind of event starts them--gateway vs. tag is moot.) Some guidance: > [@Managing multiple asynchronous threads](https://forum.inductiveautomation.com/t/managing-multiple-asynchronous-threads/37185/2): > > To manage long-running jython threads through scripting restarts, you need to: Place the thread object in a dictionary that retains its content through script restarts. I used to recommend the dictionary from system.util.getGlobals(), but that is no longer suitable. I created a free [Life Cycle Module](http://forum.inductiveautomation.com/t/system-util-getglobals-not-persisted-across-designer-save/33869/14) that provides such dictionaries going forward. Write the asynchronous function’s loop so that it regularly checks [Thread.interrupted()](https://docs.oracle.com/javase/8/docs/api/java/lang/Thread.html#interrupted--), particularly after any java I/O operations.
