Subject [jira] [Created] (SYNAPSE-1106) OOM with large responses where it involves content-aware mediation in response path
Date Fri, 31 May 2019 23:52:00 GMT
Madhawa Gunasekara created SYNAPSE-1106:
-------------------------------------------

             Summary: OOM with large responses where it involves content-aware mediation in
response path
                 Key: SYNAPSE-1106
                 URL: https://issues.apache.org/jira/browse/SYNAPSE-1106
             Project: Synapse
          Issue Type: Bug
            Reporter: Madhawa Gunasekara
            Assignee: Isuru Udana Loku Narangoda


Axis2 MessageContext class[1] 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 as shown in [2]. Because of the retained ThreadLocal variables, Passthrough
threads consumes a huge amount of memory which leads to OOM.
