That it's not handling enough concurrent clients? Those connection reset messages that were in your log? Do you have defined performance goals are you simply trying to make it not sluggish ? Those connection resets - I don' t know if they're normal or not. Should I be worried about it? I guess I'm trying to find the *reason* why this performance issue exists.

Hi, thanks for the insights. I've done what you suggested, and the load does look better, but still sluggish. The machine's are not swapping, simply JVM's max memory is 2GB. Our RAM is 4GB.

Re: Performance issue
The OS responds fine even when tomcat responses are slow. The kernel is configured (max connections, file descriptors, semaphores, shared memory, etc). Though i'm not sure whether the tuning is optimal or not. I think its probably its how the app manages connection, and probably GC? DBCP and Cayote HTTP1/1 isn't configured by the way. Would these help? If I configure DBCP, would it effect the code? Sorry for the lame questions, I'm considerably new at this. And thanks for all your fast responses.

The result is that all java app's (tomcat, console, what ever) crashes instantly. But the other system tasks keep running.

Re: Cluster Pure Tomcat with Hardware Load Balancer
Here are 2 interesting articles: http://www.onjava.com/pub/a/onjava/2004/03/31/clustering.html http://www.onjava.com/pub/a/onjava/2004/04/14/clustering.html?page=1 Since you do have a hardware load balancer, the article may not make much sense. However, if your concern is mainly session persistency, I guess you should refer to your hardware load balancer vendor for possible configurations to support megaproxy ISPs. Unless you want to opt for Tomcat's clustering feature, it would replication the session throughout all cluster nodes, which *could* solve your problem.

Hi
This question comes up alot on this list. The fix is to put your xml parser
before the tomcat one in the CLASSPATH. ie xalan.jar;xerces.jar;xml.jar
This will avoid the less functional classes in xml.jar being used when you
really want the newer classes. You can make the change in tomcat.[sh|bat]
for tomcat 4.0 In 4.0 I think the WEB-INF/lib is
automatcally searched b4 the system classpath, so no problems like this.
If you want more detail search the list archive.
