APAR status
Closed as program error.
Error description
The HTTPAsyncRequest and SOAPAsyncRequest nodes can leak SSLSockeImpl objects in the java heap. This is caused by failure to create a java local stack frame when creating java objects from an intermediate thread used by the nodes to monitor for incoming tcp/ip data associated with a response message. This can result in Java OutOfMemory errors being thrown and the Broker either hanging or restarting.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: All users of WebSphere Message Broker V8.0 or IBM Integration Bus V9.0 using the HTTPAsyncRequest or SOAPAsyncRequest nodes with SSL. Platforms affected: z/OS, MultiPlatform **************************************************************** PROBLEM DESCRIPTION: When making asynchronous webservices requests over SSL using either the HTTPAsyncRequest or SOAPAsyncRequestNodes SSLSocket references are leaked leading to exhaustion of JVM Heap memory. This can lead to Java OutOfMemoryErrors being thrown unexpectedly which may cause the Execution Group to restart. There are a number of resource name changes between WebSphere Message Broker and IBM Integration Bus Version 9.0.
