I’ve seen this problem a number of times and appears to be due to the process not closing down properly – possibly a Windows thing. This leaves the pid file in the processes directory. I think all the GUI does is check for the presence of this file and if it finds it shows the process as ‘up’ even though it is definitely dead.
I usually check for this file and the cmd_port (in the same directory) if I have this type of problem and delete them once I’ve confirmed using task manager that no hciengine is running for the process.
