problem wiht user and group for apache

[christoo]

Hi.

This is my problem:


[root@colivaresc include]# /opt/lampp/lampp stopapache
XAMPP: Stopping Apache with SSL...
PHP Warning: Module 'pgsql' already loaded in Unknown on line 0
httpd: bad group name penoles
[root@colivaresc include]#

Why there says :"bad gropu name penoles" (I wrote penoles like name group), but why is a bad name...

what happend?? when I just installed it didn't appear.
