Sun Application Server Platform Edition 8.2 Memory Leak!!

Hi there,

I've been testing a benchmark tool and been used App Server with Adventure Builder deployed as my SUT.

What happens is that I've found that the server crashes within few minutes with a memory leak problem. I was testing a version that has already set a timeout to the file descriptors and it stayed up and running for some hours, but we can observe the memory decreasing too.

I've used the netbeans profiling with a "no-alterations" App Server and it crashes after 20 minutes or so.

I've associated the increase of memory (about minute 4) with the creation of threads called iMQReadChannel that kept running until the server crashes.

Can you help me with that?

Is there a bug fix for this?

By the way, can anybody tell me some applications based in web services that I could use as a SUT? it could be some BPEL examples..

Thanks in advance

What exactly are the symptoms of the crash? If it's actually a crash and a core dump, then if you can provide more details on that (hs_err_pid file and any associated messages), we can file a bug against the JVM. If you get memory exceptions, what specifically do they say?

Also, which JVM are you actually using? There are some known bugs with JDK 1.5.0_06 and earlier around memory and file descriptor usage; we recommend that you use JDK 1.5.0_09 or a JDK 6.0 beta. For that matter, you will see better performance in general with version 9.0 of the appserver
