Hi Oyundalai, Those 23M shown in top are the amount of shared memory being used, and is not the amount being used by each individual process.
Out of interest, because I can't find it in your email, which version of tomcat are you using?. And also have you tried jdk1.3, as this is a more proven series of JVM's?
