Tobii EyeX Engine Lockup and Possible Memory Leak

[R]

Hi,

I have modified the MinimalStatusNotifications.c file from the C++ SDK to reproduce an issue we ran across in our development. After many connections and disconnections (~1000-2000) from the engine, it a) appears to leak memory b) eventually gets into a state where calling the cleanup functions (txShutdownContext, txReleaseContext, txUninitializeEyeX) will hang. When I open Windows TaskMgr while this sample is running, I see “Tobii EyeX Engine (32 bit)” is running and gets up to ~106MB of memory before the condition occurs. It starts out at ~48MB. Is there an easy way to get you the modified file to reproduce what I’m seeing?

The EyeX Engine version I currently have installed is 1.9.4.6493.

Thanks

Hi @Grant,

Can you let me know what components and versions need to be updated to resolve this issue?

Thank you!

Hi @randr, sure thing.. please uninstall all existing Tobii software on your system and upgrade to the latest Tobii Interaction Engine and Eye Tracker Drivers Bundle which you can get @ http://developer.tobii.com/downloads/

Kindly let us know how it goes.
