When I try to run importaddress using the core client it takes a long time to execute, over 10 minutes, even though I have supplied a "false" argument for rescanning. For example:
bitcoin-cli importaddress "32jdC23ABv86M2ptiqMzFzCaufBtE2NCdN" false
When I run this, it takes so long to compute that it times out with "unable to connect to server error". If it is not rescanning, what is it doing? Why is it taking so long just to add an address to the wallet?
(note that adding a label field makes no difference, it still hangs)
