No i don't have tried at this time, i'm in "beta" version so i try to anticipate this problem before i was at this part :) Ok i will try, thanks > By the way: if you start getting out of memory errors as you deploy more > copies, > make sure you have enough perm space configured in your JVM options. > Hibernate can generate a lot of classes, and lots of copies of these classes > can > consume a lot of perm space. I'm glade to discuss about that. I'm aware that hibernate is a big giant library wich use lot of memory. But when i launch tomcat with this env vars : JAVA_OPTS="-XX:MaxPermSize=512m -Xms24m -Xmx512m" Tomcat looks like not really care about the memory i grant to JVM. It's seems that tomcat have the memory but don't give to the différents contexts I have a poor "Free memory" at each time... Is it something i miss or not ? Thanks again to you Jerome Lepage AKEROZ
