Subramanyam Ramanathan updated AXIS2-766: ----------------------------------------- Attachment: test2.xml XML file being posted to axis2 web service. > Axis2 High memory usage, OutOfMemory exception > ---------------------------------------------- > > Key: AXIS2-766 > URL: http://issues.apache.org/jira/browse/AXIS2-766 > Project: Apache Axis 2.0 (Axis2) > Type: Bug > Environment: Red Hat Enterprise Linux ES release 4 > Axis2 version 1.0 > Tomcat 5.5.17 > jdk 1.5.0_04 > Reporter: Subramanyam Ramanathan > Attachments: Axis2SampleDocLit.wsdl, Axis2SampleDocLitServiceSkeleton.java, > PostXmlToAxis.java, SoapSender.java, test2.xml > > 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 also filled in the > Skeleton class with the same code as given in the user guide. > 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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
