Hi, I like to share the solution I have so far.
I am involved in implementing a middleware which has to perform lots of web service calls, also in parallel. This means we cannot just share a service client for all our requests. I've found through debugging axis2 code that calling serviceClient.cleanup(), after I performed my web service call, removes the generated anonymous AxisService from the AxisConfiguration. I am assuming that this will prevent the OutOfMemoryError, but I could not verify it in tests yet. Can someone confirm that using the serviceClient this way is a good idea? Thank you, Matthias. -----Ursprüngliche Nachricht----- Von: Deepal jayasinghe [mailto:deep...@gmail.com] Gesendet: Samstag, 7.

The reason behind this is whenever you create a serviceClient, it creates an AxisService and added to AxisConfiguration. In order to overcome this issues, create one service client and reuse that.
