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

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

For more information, please see the following Wikipedia entries:
