Hi Nethanel,
Can you answer me the below questions?
What is your axis jar version?
what is the xml size u send for parsing?
What is the application server you are using?
What is your Heap memory size?

> I got out of memory error and when i analysed heap dump, i was getting infinite active
references of deserialization and xmlreader.When expand Deserialization context,XMLReader
reference is there and when expand XMLReader,Deserialization reference is there.It seems to
be circular reference.The sample output of heap dump is given below.
