Yes, we experience same problems with Tomcat 5.5.17 We did a lot of tests and profiling instrumentations (Jprofiler powered) on many environments : Win32/Linux, JDK1.4.2_12, JDL 1.5, Tomcat 5.5.17/5.5.20 Same problem: many redeployments (or reload) of a webapp throw an OutOfMemory for the PermGenspace. If you monitor your Jvm with Jvmstat tools you would see this non-heap memory never been released... The problems seems to be located with Cglib classloaders referencing policy. There is a lot of topic on the Net, which may be interessing to read, but noone seems to have found a valuable solution. (Increasing the PermGenspace is NOT a reasonable solution) The only way we found to fix it is to change the JVM. Indeed if we use the BEA Jrockit 1.4 JVM, the application can be deployed as many times you want... Please give some news, if you find something useful RC > -----Message d'origine----- > De : Jon Miller [mailto:[EMAIL PROTECTED] > Envoyé : mardi 28 novembre 2006 01:38 > À : Tomcat User List > Objet : Memory leaks on webapp redeploy > > Hi all, > > > I think I read in a FAQ that even using a singleton in your > app will cause memory leaks?
