[erlang-questions] Why does the restart strategy "{one_for_one, 10, 10}" still kill my application?

[Shelton Tang]

I am writing an application. In myapp_sup:init, I use the restart
stragey "{one_for_one, 10, 10}".  For some reason, one process in the
three will exit since an invalid socket operation.  However, I found
the entire tree will be killed in this case.  I use "transient" as the
type and also try "temporary".  But same result.  Can anybody give me
a hand?
