[jira] [Resolved] (AXIS2-5874) Memory leak when trying to getInputStream() from an External Repository data through AXIS

JIRA jira@apache.org

     [ https://issues.apache.org/jira/browse/AXIS2-5874?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andreas Veithen resolved AXIS2-5874.
------------------------------------
    Resolution: Invalid

The stack trace indicates that the OOM error occurs before the proxy method returns and the heap dump shows a single PartContentOnMemory object corresponding to a large (750MiB) MIME part. Obviously the memory used to store the MIME part content can't be released before the proxy returns. There is therefore no memory leak here.

Please note that this is a bug tracker, not a support forum. When creating a bug, provide evidence for the claims made in the bug report.

> We are using AXIS WS to connect and download files from an external repository .We are using SOAP based webservice calls download an object. The API returns a DataHandler object, from where we are getting the input stream. We have tried closing the inputstream object but even after the close call we can see that the memory is still holding the stream, and eventually the client machine is running out of memory.Any help on this would be highly appreciated.
> Our client code is as shown below
> URL url = new URL("http://"+host+"/ws/CntSrvc.svc?wsdl");
> CntSrvc_Svc cService = new CntSrvc_Svc(url);
> CntSrvc cntSrvcClient = cService.getBasicHttpBindingCntSrvc(new MTOMFeature());
> InputStream in = null ;
> in = cntSrvcClient.download(contextIDString).getInputStream();
> // write in to a file.
> //closing the input stream
> if (in != null){
>  in.close();
> }
> [Note;] Our client code runs under tomcat container, and this acts as a server to other services.
> [Note:]We have created a sample client without using AXIS, where our client connecting to external repository and download content.Here we donot see any memory leak.Our investigation proves that its when we use AXIS and getinputstream() the memory is leaking, input stream is not closing.Our current framework demands AXIS hence we would like to get a solution or workaround for this issue
