Bluetooth low energy - Input/output error

When I do

hcitool lescan

sometimes I saw this error 

Set scan parameters failed: Input/output error
or
Set scan parameters failed: File descriptor in bad state

I know i can reset the bluetooth interface.

However, is it possible to see the log or get any information to know the root cause of this error?

Thanks
