Re: Tomcat using VERY LARGE Memory (URGENT!!!!!!!!!)
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?
