Leap motion service using 80-90% CPU

[happe]

Hi.

I work for a company that develops interactive solutions for museums and such. Recently, I developed a thing in Unity, where I used the tool tracking feature of a Leap Motion. For that reason, I'm using Leap motion SDK Windows version 2.3.1, since that is (as far as I can tell) the last version that features tool tracking.

Lately, we have been getting reports that the solution starts to lag every day after about 5-6 hours of continuous play. When troubleshooting I noticed that the Leap Motion Service was using over 80% CPU. When I restarted the service, the CPU usage went down to about 1%, and the lag disappeared.

Does anyone know what could cause this?

Thank you,
Hannes

The issue you're running into may be due to bad memory allocation in the service. The last update to the V2 software was a few years ago. Since the issue appears to be resolved when restarting the service, I would recommend writing a script to restart the service intermittently to alleviate this issue.
