When a process traps exits the incoming exit signals coming from linked processes are converted by the run-time system into messages that remove_first_job() -> First = ets:first(?POOL), {_, Key} = First, exit(Key, cancelled), ets:delete(?POOL, First). insert_job() -> {Pid, _} = spawn_monitor(fun() -> worker() end), ets:insert(?POOL, {{erlang:monotonic_time(seconds), Pid}, []}), Pid. 12.4 Process Termination. When a process terminates, it always terminates with an exit reason. The reason can be any term. A process is said to terminate normally, if the exit reason is the atom normal. A process with no more code to execute terminates normally. A process terminates with an exit reason {Reason,Stack} when a Erlang certainly has an appropriate mechanism for that, and it's part of the receive construct: receive Match -> Expression1 after Delay -> Expression2 end.

init ([]) -> process_flag (trap_exit, true), {ok, ok}. But I couldn’t leave it at just that. I had to seek help, and so I showed it to my senior colleague Nicolas, I had then devised a test which would reproduce this neatly. He cut it down a bit, and I boiled it to the broth you see here and can compile and run for yourself.

See Exit Reasons. A process can terminate itself by calling one of the following BIFs: exit(Reason) erlang:error(Reason) erlang:error(Reason, Args) The process then terminates with reason Reason for exit/1 or {Reason,Stack} for the others. A process can be set to trap exit signals by calling: When a process is trapping exits, it will not terminate when an exit signal is received. Instead, the signal is transformed into a message {'EXIT',FromPid,Reason} which is put into the mailbox of the process just like a regular message. Not being an Erlang programmer and just from the documentation of exit , I'd say, that exit requires a process id as first argument whereas you are passing an atom (?SERVER) to it. Try. exit(whereis(?SERVER), ok). instead (whereis returns the process id associated with a name, see here) A process can subscribe to another process’s exit signal by establishing a “link” with that process.

If Reason is the atom kill, that is, if exit(Pid, kill) is called, an untrappable exit signal is sent to Pid, which unconditionally exits with exit reason killed. erlang:external_size(Term) -> integer() >= 0 For exceptions of class exit, that is, the code called exit(Term), {'EXIT',Term} is returned. For exceptions of class throw , that is the code called throw(Term) , Term is returned. Reason depends on the type of error that occurred, and Stack is the stack of recent function calls, see Exit Reasons .

Erlang is designed for massive concurrency. Erlang processes are lightweight (grow and shrink dynamically) with small memory footprint, fast to create and terminate, and the scheduling overhead is low. 12.2 Process Creation. A process is created by calling spawn:
