Description

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.
