Resolution

The httpConnector Resource Template was modified with a larger Response Buffer Size (B) , in this case from the default (8192) to 50000. httpConnector is the name of the default HTTP Connector used to invoke the exportResources API. This shared resource is created while configuring TIBCO ActiveMatrix BPM server. For more details on the HTTP Connector configuration, refer to TIBCO ActiveMatrix BPM SOA Administration > Managing Resource Templates > References > HTTP Connector .
