Debugger unable to terminate

I am developing an application that uses several RS232 devices. When breaking on a break point with the debugger often results in an error: “The debugger was unable to terminate one or more processes. [0195C] Main.vhost.exe: Access is denied.”. The most frustrating thing about this is that I have to reboot my computer to recover. Any ideas why this is happening or how to terminate without a reboot?

I remember I had similar problems but can't recall details. Definitely it was not related to any external communication devices. I was able to stop processes (including VS) from the task manager. Did you try TM to kill tasks?

Yes. I have tried TM and couldn't terminate the process (it seems like a process of VS still remain running after it was supposedly closed)

I've seen problems where a thread failed to terminate because it was still being used by a COM port.   I had to unplug the cable to get the COM port released by Windows, which then allowed the thread to close.
