Strange Port tracked

[timknip]

hi,

It's quite new for me to use nginx as the webserver, nginx 0.7.65 + php
/fpm on freebsd,  which was installed on Apr 28th, 2010. I configured
the server to listen on Port 80 as seen below.

    server {
        listen      80;

My php script will create a folder by domain name each time it detect a
different domain. I saw a strange xxxxx:4511 folder created on Jan 13th,
2011. Also owner of all php files and folders are changed to 1005 . I
double checked /etc/passwd and the max user id there is 1003.

 Is it possible that my nginx/phpfpm server is hacked?  Please advice!

cheers
Tim
