[erlang-questions] error_loger after run "erl -name foo"

[kuangyel2000@REDACTED]

 I run "erl -name foo" on cmd of windows, it show: 

{error_logger,{{2013,7,8},{15,51,6}},"inet_parse:~p:~p: erroneous line, 
SKIPPED~n",["c:/Windows/System32/drivers/etc/hosts",1]}
=INFO REPORT==== 8-Jul-2013::23:51:06 ===
inet_parse:"c:/Windows/System32/drivers/etc/hosts":1: erroneous line, 
SKIPPED
Eshell V5.10.2 (abort with ^G)
foo@REDACTED>

but I run "erl -sname foo"
it is OK. it has no error_logger.

my file: c:/Windows/System32/drivers/etc/hosts
127.0.0.1 localhost
::1 localhost
127.0.0.1 sgwin712.com
127.0.0.1 sgwin712

is it OK?
What is the problem?
