Since cowboy_sup received an exit signal of 'killed' from cowboy_listener_sup, doesn't that imply that it was (explicitly) killed with exit(Pid, kill)?


>> I have a gen_server that seems to be crashing for some reason and the supservisor is not restarting it.  The child spec is one_for_one, permanent and the error log is below.  All i see is the crash report but no attempt at a restart.  Is there any way to figure out why the supervisor would not restart it?
