> MessageContext class store messageContext object in a ThreadLocalVariable where it doesn't clear created ThreadLocal variables properly. Therefore synapse passthrough threads contain created the Theadlocal variable which refers to the created soap envelope during the mediation level. Because of the retained ThreadLocal variables, Passthrough threads consumes a huge amount of memory which leads to OOM.
