Could you please log a jira bug and upload your test code both on the server and client. Am really surprised. I have been testing performance for months now and i haven't seen this behavior.

Hi, I have been trying out Axis 2.0 over the past week, with the configuration : Axis2 version 1.0 Tomcat 5.5.17 jdk 1.5.0_04 I have tried using the sample "Axis2SampleDocLitService" that has been given. I generated the stubs and skeletons using the wsdl provided with the axis2 distribution (samples/wsdl/Axis2SampleDocLit.wsdl) , as shown in the user guide, using the xmlbeans option for data binding. I have a http client which I use to post the xml request to the server, and I got proper responses when I tested it with the client. However, I have noticed that when I pump requests at a rapid rate, the memory usage keeps on increasing rapidly (checked using jmx console), in some cases ultimately leading to a jvm crash with an OutOfMemory Exception. This was occurring when default mx(which is 64M) was used. I also tried setting the JVM mx option to 128M (-Xmx128M) and ran the test again. However, the memory usage keeps increasing all the way till it reaches 128 Mb, too, where it again crashes if I continue pumping further. If I stop pumping requests at around that time, and wait for around half an hour, I notice that the memory usage begins to reduce, and slowly come back to the original value (10M approx.) upon forcing a GC. I have also deployed axis1 on the same tomcat installation, with the intention of comparing performance. When I try the same test there, ie, pumping requests, I don't find any alarming memory increase. Why is so much memory being used, and why does it grow to fill however much memory is available ? Is it a memory leak, or is there any way I can limit the amount of memory being used ? The memory usage does come down, but it takes a very long time for this. This would surely affect the performance of any webservice I try to deploy with axis2, and it may even result in the service being unavailable because of a crash. Could you please help me out ?
