Hi Guys,
This is nothing to do with MYECLIPSE IDE but i am trying to see if anyone else has noticed this TOMCAT server issue.
I am using TOMCAT 5.0.28 With JDK1.4.2.08 WIN2K server box and when i do Stress testing i have noticed that TOMCAT Private Bytes going up and never come to normal even after Stree testing.
I am also using Optimize it to see if there is any application leaks..Heap seems to be normal going up and coming down when GC happens but Tomcat chews up memory and never comes back to the same level as when start it.
This seems to be behavoir of TOMCAT 5.X and 5.5.X also does anyone come across anything like this..I have done JAVA_OPTS here setting the JVM to run as -server and also setting -Xms and -Xmx options to reasonable limits..I never had out of memory exception .
Please write back to me if anyone knows why this is happening or what may be the cause for this.Stress testing i have noticed that TOMCAT Private Bytes going up and never come to normal even after Stree testing.
I didn’t understand this: “Private Bytes” and “Stree”?
Heap seems to be normal going up and coming down when GC happens but Tomcat chews up memory and never comes back to the same level as when start it.
Ahhh, I’ve seen this in production pretty common, but i haven’t profiled it before to see why it keeps going up. I just assumed Tomcat is an aggressive cacher.
You could try running the same tests on Jetty and seeing if it exhibits identical behavior.
Hi Riyad,
Thanks for your reply.
Private Bytes is the Memory of Tomcat Usage in WIN2K server and Stree was a Typo…It is meant to be Stress .Anyway i think lot of people have encountered this with TOMCAT but no one has really raised this issue in Apache forums.Moreover i am suprised that such a popular Web Server is having this kind of issue.
