Madhawa Gunasekara updated SYNAPSE-1106:
----------------------------------------
Description: 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. (was: Axis2 MessageContext class[1]
store messageContext object in a ThreadLocalVariable where it doesn't clear
created ThreadLocal variables properly.)
> OOM with large responses where it involves content-aware mediation in
> response path
