All EXE/Script sensors that have the same Mutex (Mutual Exclusion) name are executed serially (not simultaneously). This is useful if you use a lot of sensors and want to avoid high resource usage that is caused by processes that run simultaneously.

To make sure that your executable or script files are not executed simultaneously, please define the same Mutex name for all EXE/Script sensors. If you use different Mutex names, they can be executed at the same time.

For more information, please see the following Wikipedia entries:
