<br />
How do you gracefully exit from a state_timeout in a gen_statem? Generally, for a gen_statem, I can return “stop” or {stop, Reason} from a state function and the statem will terminate. However, if I use a state timeout method, returned from init:<br />

<br />
The new_state(state_timeout, Info, State) method is called after 2000. Returning “stop” from this given an error…:<br />

Can you post the whole printout?<br />
The truncation hides where the process has crashed.<br />

What can I return from this function to gracefully exit? Can this be done with state_timeout? If this is an obvious question, please point me in the right direction. The documentation here:http://erlang.org/doc/man/gen_statem.html doesn’t seem to mention any return from the state_timeout.<br />
<br />
Thanks!<br />
