A minor but annoying problem I see from time to time is that a few of my really small compiled Labview programs seems to use 1 full CPU core after a few days of running. In short: Labview 2015 Windows 10 Compiled exe-file of program with 60s loop time, see below. At start uses 0% CPU in task manager After a few days (a week) it uses 16% CPU on a 8 core PC, I assume this is one full core. CPU load stays even if I stop the exe and keep it open. If i close the exe window and open it again I am back at 0% CPU again. Just noticed that the idle Labview development system also uses 16% CPU? I am not sure if the CPU load is real, or some kind of a artifact,so far I've not noticed the PC slowing down. Task mananger shows heavy CPU load from simple program running for a week: After closing the app Kör datorn and opening it again I get 0% CPU: Code, the program just writes to a file every minute:

I remember an old thread mentioning that just leavning the LV start open for a day could cause it to spin wildly, i wonder if that's connected to this. /Y

Simple labview program uses 100% CPU after some days?

Solved!

Yamaeda, I never see it if I only run executables, so I think it is related to the development system.
