OutOfMemoryException #44

Open AdamoT opened 5 years ago

AdamoT commented 5 years ago

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 5 years ago

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

alexandre-leites commented 4 years ago

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

AdamoT commented 4 years ago

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 4 years ago

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?

hvanzyll commented 3 years ago

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