Insane memory usage by apache?!?

I'm not exactly sure what to make of this. I have personally never seen this before:

9563 nobody 9 0 534M 534M 534M S 0.0 113.2 0:00 httpd
9562 nobody 9 0 534M 534M 534M S 0.0 113.2 0:00 httpd
9559 nobody 9 0 534M 534M 534M S 0.0 113.2 0:00 httpd
9560 nobody 9 0 534M 534M 534M S 0.0 113.2 0:00 httpd
9561 nobody 9 0 534M 534M 534M S 0.0 113.2 0:00 httpd
2828 root 9 0 534M 534M 534M S 0.0 113.2 0:55 httpd
22221 root 9 0 28188 23M 9316 S 0.0 5.0 0:05 java
This server, as you can see is running tomcat ( version 4 from layer1.cpanel.net ). Now there is not much activity on this server. A few low resource sites and I can't seem to pick whats causing apache to go so high. I'm not exactly sure that the numbers being spat out above are correct.. is this possible?

I have put a limit on the mem and space usage for apache, but it looks as if that is being ignored. Anyone have a clue what the problem might be?
