    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 @randr, we have confirmed the presence of a memory leak when using a high number of connection. We intend to fix this in an upcoming release. Many thanks for reporting this!

    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.
