Instalation Problem Fedora FC14 i386

I just trying to start it on clear Fedora core 14 system.  JDK 1.6.23
Version:6.0Build:15772File size:298.9 Mb
I did not setup any database on this server. I don't have any data deryctory or any config. I just extract tar.gz to /usr/TeamCity/  and run  runAll.sh
I have 1GB ram.

When i start i get this error.[2010-12-09 21:52:52,690]   INFO -   jetbrains.buildServer.SERVER - Starting TeamCity server
