Moar data from affected nodes. I?ve listed process by `current_function` and
sorted by occurrence
<details>
<summary>current function count/group script (click to reveal)</summary>
```erlang
io:format("~p", [
lists:keysort(2,
maps:to_list(lists:foldl(
fun(Elm, Acc) ->
case Elm of
{M, F, A} ->
N = maps:get({M, F, A}, Acc, 0),
maps:put({M, F, A}, N + 1, Acc);
Else ->
Acc
end
end,
#{},
lists:map(
fun(Pid) ->

undefined -> [];
Info -> proplists:get_value(current_function, Info)
end
end,
processes()
