[erlang-questions] erlang:halt() cannot terminate the Erlang VM

[skyman]

Hi all,
I encounter this problem: erlang:halt() cannot terminate the Erlang VM. Then I user "kill -USR1 erlpid" to kill the Erlang VM process, and get an Erlang crash dump, it indicates that there are some "Scheduled" processes.
I want to know  under what cases erlang:halt() cannot terminate the Erlang VM, for example, existing  "Scheduled" processes?
Thanks in advance!
