Hi tj, I really don't know what could be the issue. Maybe some lock inside
the bach program or something like that.
Anyway, you could try this simple mojo app to see that subprocesses should
not block among them:
#!/usr/bin/env perl

> $c->inactivity_timeout(180);
> my $n = $c->param('n');
> my $sp = Mojo::IOLoop::Subprocess->new;
> $sp->run(
> sub { `sleep $n` },
> sub {
> my $pid = shift->pid;
> $c->render( text =>

Just run it with morbo, and then from one browser window go to
http://localhost:3000/30, and from other browser window go for instance to
http://localhost:3000/1, etc
You should be able to run many of them simultaneously, and the pids for
each subprocess should be different.
BR,
