The SIL Threads section shows a list of all the scripts running at that moment and how long they have been running for. To find this list go to Power Apps Config → Runtime → SIL Threads
This is a good place to identify scripts that may be ‘stuck’. Perhaps they are waiting on an external system to complete a process or perhaps there is a problem with the logic. Regardless, this section helps you catch this behavior and, if necessary, kill the script that has become ‘stuck’. However, it should be noted that killing the thread can have adverse results in the main application (Jira or Confluence) and should only be used in case of emergency's.
If a script is not running or has completed, it will not appear in this list.
Note that the results of the SIL Executions threads it only for the Data Center node the user is currently on and does not represent performance results from the other nodes. This may be changed in the future.
