OutOfMemoryException

The issue is raised every time I leave my application running for about 3 days. I don't have a full stacktrace, because the exception is caught in AppDomain.CurrentDomain.UnhandledException but it's something like this:

The system I'm running has 32GB of RAM and at the point when this exception is invoked I don't observe any huge system memory consumption.

Azmarel commented

Hi, I have the same problem. Memory leak diagnosed with a profiler.

alexandre-leites commented

Have you guys moved to other lib or fixed it somehow?

AdamoT commented

Not really. The most important functionallity for me was to be able to get/change default system audio device, which is an undocumented windows feature and I haven't found any other lib that even attempts to implement it. If someone knows about one, please let me know. For now, I just restart my service when this issue happens

Luckz commented

The API as used by the 1.x GUI doesn't seem to have this problem, or doesn't trigger it, so perhaps it's a matter of using a specific working version?

I have the same problem, it was only running a few hours
