OS: Red Hat Enterprise Linux AS release 4 (Nahant Update 2) I have 2G ram for JVM, but I would like to stick with 1G if its possible.
With the change of JVM settings still no positive result.. therefore I will switch back to Xms and Xms as you say. (with a same value -- 1G may be?). Do you recommend upgrading to Tomcat 6? Thanks Chuck for your responses, much appreciated! /Maduranga On Thu, Jul 3, 2008 at 4:49 PM, Caldarale, Charles R <[EMAIL PROTECTED]> wrote: >> From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] >> Subject: Tomcat Runs OutOfMemory (Not at repeated WAR deployments) >> >> I changed many JVM parameters with no luck and currently it is: >> -server -Xms512m -Xmx2048m -XX:NewSize=128m -XX:MaxNewSize=128m >> -XX:SurvivorRatio=4 > > I would strongly recommend against playing with NewSize, MaxNewSize, or > SurvivorRatio; getting them even slightly out of kilter can foul things up > pretty quickly. > > What platform are you running on?
