[jira] Commented: (AXIS-2266) Axis Memory leak in v1.3

["Dies Koper (JIRA)" <ax...@ws.apache.org>]

    [ http://issues.apache.org/jira/browse/AXIS-2266?page=comments#action_12368640 ] 

Dies Koper commented on AXIS-2266:
----------------------------------

It is difficult to investigate a memory leak with only a client.
If you would like someone to look at your problem, please provide a complete test application (WSDL + client + impl) that shows the memory leak (when run long enough, or when run in a profiler).
The problem occurs at the client side? Server? Both?

> Axis Memory leak in v1.3
> ------------------------
>
>          Key: AXIS-2266
>          URL: http://issues.apache.org/jira/browse/AXIS-2266
>      Project: Apache Axis
>         Type: Bug
>   Components: Basic Architecture
>  Environment: Solaris and Windows
>     Reporter: Alan Yu
>     Priority: Critical
>  Attachments: SOAPInboxStorageHelper.java, memory_leak.GIF

> We had a memory leak problem in the old axis version 1.1.  But due to the low traffic, we didn't quite notice it. 3 weeks ago, the traffic is increased and this problem had emerged.
> I did some investigation and used the Optimizeit to do profiling. I then decided to upgrade to latest 1.3 which the release notes claims the memory leak problem is fixed.
> But unfortunately, this is still there.
> We use axis to send a request to do login validation on a remote web site. No stubs is generated. The code is simple as follows:
>   public InboxStorageAccessResult prepareInboxStorageAccess(
>       String url, String inboxDID, long inboxServiceKey, String domain, String site)
>       throws J2ContainerException, PoolExhaustedException
>   {
>     String[] loginParameters = null;
>     try {
>       SOAPConnection connection = getConnection();
>       Service service = null;
>       try {
>         service = connection.getService();
>         Call call = service.createCall();
>         if (log.isDebugEnabled()) {
>           log.debug("Initiating SOAP call.  Address=" + url);
>         }
>         call.setTargetEndpointAddress(url);
>         call.setOperationName(new QName(loginUrn, "login"));
>         loginParameters = new String[] {
>           loginId,
>           loginPassword,
>           inboxDID,
>           domain, // domain.
>           inboxServiceKey + "",
>           site
>         };
>         if (log.isDebugEnabled()) {
>           log.debug("calling: \t" + url);
>           log.debug("method: \t" + loginUrn);
>           log.debug("loginId= " + loginId +
>                     "; loginPassword=" + loginPassword +
>                     "; inboxDID = " + inboxDID +
>                     "; domain =" + domain +
>                     "; inboxServiceKey = " + inboxServiceKey);
>         }
>         String soapResult = ((String) call.invoke(loginParameters));
>         return new InboxStorageAccessResult(soapResult);
>       } finally {
>         try {
>           connection.cleanup(service);
>         } catch (ConfigurationException e) {
>           log.error("ConfigurationException: loginParameters: " + StringUtil.joinWithCommas(loginParameters), e);
>           throw new TwaRemoteException("Call to electric mail login failed", e);
>         }
>         returnConnection(connection);
>       }
>     } catch (ServiceException ex) {
>       log.error("ServiceException: loginParameters: " + StringUtil.joinWithCommas(loginParameters), ex);
>       throw new TwaRemoteException("Call to electric mail login failed", ex);
>     } catch (RemoteException ex) {
>       log.error("RemoteException: loginParameters: " + StringUtil.joinWithCommas(loginParameters), ex);
>       throw new TwaRemoteException("Call to electric mail login failed", ex);
>     }
>   }
> The leak are at char[], int[], String and java.util.Hashtable. The attached profiler snapshot is a trace for leak from Hashtable.
> I tried to add a few cleanup method like below
>     public void cleanup(Service service) throws AxisFault,
>         ConfigurationException {
>       log.debug("[in] axisCleanup");
>       if ( service == null ) {
>         log.debug("service null");
>         return;
>       }
>       AxisEngine ae = service.getEngine();
>       if ( ae == null ) {
>         log.debug("axisEngine is null");
>         return;
>       }
>       
>       MessageContext mc = ae.getCurrentMessageContext();
>       if (mc != null &&
>           mc.getRequestMessage() != null &&
>           mc.getRequestMessage().getSOAPEnvelope() != null)
>       {
>         log.debug("****** clean envelope ******");
>         mc.getRequestMessage().getSOAPEnvelope().removeBody();
>         mc.getRequestMessage().getSOAPEnvelope().removeContents();
>         mc.getRequestMessage().getSOAPEnvelope().removeHeaders();
>         if ( mc.getRequestMessage().getSOAPEnvelope().getRecorder() != null) {
>           log.debug("****** clean recorder ******");
>           mc.getRequestMessage().getSOAPEnvelope().getRecorder().clear();
>         }
>       } else {
>         log.debug("no envelope is available");
>       }
>       ae.cleanup();
>       if (ae.getGlobalRequest() != null) {
>         ae.getGlobalRequest().cleanup();
>       }
>       if (ae.getGlobalResponse() != null) {
>         ae.getGlobalResponse().cleanup();
>       }
>     }
> but it doesn't help.  The envelope part is null and I got "no envelope is available" from my debug printout.
> Because of this memory leak, we have to restart our web server once a day.
> I'd appreciate it if you can provide any solution to fix the problem.
> Thanks,
