Always getting OOME's running inspections build

Hi

     1st I must say i'm loving the polished interface and ease of use of TC.
     I just got the latest teamcity (not EAP) to work, and while my builds (test and integration) run fine the inspections build always OOMEs.
     The box is a ubuntu server with 2GB ram running a local agent.
     I already upped the agent's heap and permgen to big values (via the JVM settings in the runner settings for the build, set to 2048, 120 respectively) still the build always fails at 29%.    
     The project is not so big (15K NCSS) so I'm wondering why 2GB ram is not enough to run the inspections on such a project.

Any ideas?
Cheers
David
