Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server for z/OS V6.1.0 * **************************************************************** * PROBLEM DESCRIPTION: A Websphere for z/OS Application Server * * controller receives a native out of * * memory exception under load when many * * TCP/IP read failures have occurred. * **************************************************************** * RECOMMENDATION: * **************************************************************** During certain error paths the controller may run out of native storage as native storage buffers associated with TCP/IP read requests are not being released when the buffers are returned to the storage pool. The messages in the log may vary but will generally be like the following: Trace: 2011/08/04 14:15:28.999 01 t=7C41E0 c=UNK key=S2 (00000004) Description: Throw CORBA system exception exception id: CORBA::NO_MEMORY minor code: c9c2e328 from filename: ./bbocdbbm.cpp at line: 66 Trace: 2011/08/04 14:15:28.999 01 t=7C41E0 c=UNK key=S2 (04072019) Description: Java exception created from filename: ./bboocjex.cpp Method Name: createExceptionForJava(JNIEnv *, char *, unsigned int, CORBA::CompletionStatus, CORBA::Exception *, char *, CORBA::Bo olean, CORBA::Boolean) org.omg.CORBA.NO_MEMORY: Exception occured during native method call from JAVA vmcid: 0xc9c2e000 minor code: 328 completed: No at com.ibm.ws.buffermgmt.impl.ZOSWsByteBufferPoolManagerImpl.alloca teDirect ByteBuffer(Native Method) at com.ibm.ws.buffermgmt.impl.ZOSWsByteBufferPoolManagerImpl.alloca teBuffer Direct(ZOSWsByteBufferPoolManagerImpl.java:83)
Problem conclusion
The code has been changed to release any native storage buffers that have not been freed before the buffers are returned to the storage pool. APAR PM51214 is currently targeted for inclusion in Service Level (Fix Pack) 6.1.0.45 of WebSphere Application Server V6.1. Please refer to URL: //www.ibm.com/support/docview.wss?rs=404&uid=swg27006970 for Fix Pack availability.
