Case: I've deployed an application on a Tomcat 6.0 (current release). The application is a Hibernate / Stripes application.
Almost no memory is allocated due to the deployed application. Setting: -Xmx64m -XX:MaxPermSize=128m Tomcat without application uses: 27,5M (real memory) and 349M (virtual memory) Tomcat with application uses: 133M (real memory) and 367M (Virtual memory) Now if I stop this application (using the manager) the memory profile becomes: Tomcat with stopped application: 128M (real memory) and 679M (virtual memory) So stopping the application increases the virtual memory usage from 367 to 679 m and stays there! Undeploying a stopped application doesn't change the numbers. Why does stopping (or undeploying) a webapplication cause a dramatic increase in memory usage? My guesses: - Some ressources are not freed? (database connections) - Some hibernate related stuff are trapped in a circular relation circle? - Tomcat punishes me for stopping something it really liked :-) -- Morten Matras Udviklingschef GAMP Media og Blob Communication ApS Svendsagervej 42 5240 Odense NØ Tlf: 61711103 E: [EMAIL PROTECTED] T: 76 654321 W: www.blobcom.com E: [EMAIL PROTECTED]
