Re: initial memory pool and maximum memory pool in Tomcat 6.x
Thanks, Leon My limitation is on RAM. but the question really is the relationship between Memory Pool and Permgen, since some time my app will run out of Permgen. thanks.

From: Tuan Quan [mailto:[EMAIL PROTECTED] Subject: Re: initial memory pool and maximum memory pool in Tomcat 6.x but the question really is the relationship between Memory Pool and Permgen, since some time my app will run out of Permgen. PermGen size is set separately from the Java heap, using the -XX:MaxPermSize parameter. If you really need to expand PermGen, use that; however, you may well have a memory leak in your application if it's hanging on to class references when it shouldn't: http://wiki.apache.org/tomcat/FAQ/Memory http://opensource.atlassian.com/confluence/spring/pages/viewpage.action?pageId=2669 - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
