Thanks Kumar. By: Teodor Danciu - teodord RE: java.lang.OutOfMemoryError : PermGen Spac 2006-07-06 00:43 Hi, Are you using the file virtualizer? In any case, try launch the JVM with this option: -XX:MaxPermSize=128m or more -XX:MaxPermSize=256m I hope this helps. Teodor Link to comment Share on other sites More sharing options...
javydreamercsw Posted September 7, 2006 Share Posted September 7, 2006 This error occurs when the JVM runs out of space in the permanent generation heap. If the application(s) in the server use a large number of classes, the solution is to increase the value specified with -XX:MaxPermSize. If the error occurs only after the redeployment and restart of new applications, then the likely cause is that the JVM cannot garbage collect old classes that are replaced because there are references to the old classes.Post edited by: javydreamercsw, at: 2006/09/06 20:55 Link to comment Share on other sites More sharing options...

javydreamercsw Posted September 7, 2006 Share Posted September 7, 2006 Tomcat version won't make a difference. Is a known memory leak that have been bugging tomcat and many other programs that loads plenty of classes at the same time. It'll indeed help restarting the server but it brings up the question on what'll happen if you use JasperIntelligence in a production environment with many people using it at once...
