I finally managed to get my issue sorted out. After installing Tomcat on another machine to do some testing I noticed that it had the following value in the registry:
JVM Library: C:\jdk1.3.1_03\jre\bin\hotspot\jvm.dll After changing this value to the server\jvm.dll my Tomcat is performing incremental garbage collection as expected had doesn't crash when reaching it's -Xms600 limit. I was even able to lower -Xms600 to -Xms256 and everything seem stable. Thanks for all the suggestions. Any comments? Regards Jason --------------------------------- Do you Yahoo!? The New Yahoo!
