Unreal crashes after ~20 minutes: OSVR plugin is the suspect

Hello,

I’m using Unreal4 for an artistic installation schedules for december.
Currently testing the whole thing and I have Unreal4 crashing after approximately
20 minutes of idle. I’m using OSVR plugin for my VR. Here is the callstack:

Access violation - code c0000005 (first/second chance not available)

Speaker!FModuleManager::GetModule()
Speaker!FModuleManager::GetModuleChecked<IOSVR>()
Speaker!FModuleManager::LoadModuleChecked<IOSVR>()
Speaker!FOSVRHMD::UpdateHeadPose()
Speaker!FOSVRHMD::PreRenderViewFamily_RenderThread()
Speaker!FRelevancePacket::RenderThreadFinalize()
Speaker!TGraphTask<FRendererModule::BeginRenderingViewFamily'::21’::EURCMacro_FDrawSceneCommand>::ExecuteTask()
Speaker!FNamedTaskThread::ProcessTasksNamedThread()
Speaker!FNamedTaskThread::ProcessTasksUntilQuit()
Speaker!RenderingThreadMain()
Speaker!FRenderingThread::Run()
Speaker!FRunnableThreadWin::Run()

Should I contact OSVR deloppers or you have actually wrote your own plugin ?

Thanks.
Sincerely
M.

ps. It’s slightly urgent…
