Error description
When a WMB broker address space is using the MQ Java interface and a queue manager which it has already been connected to becomes unavailable, a residual value in the MQ Java native code can result in an MQ call being made with an invalid hconn value. This causes in an attempt to access freed storage and the GPF abend occurs at below Java callstack: com/ibm/mq/jmqi/local/internal/base/Native.MQCONNX Native callstack: CSQBBspiSCTX+0xd1d68950 (0x0000000000000000) ResetContextFn+0xcfbd12d0 (0x0000000000000000) Java_com_ibm_mq_jmqi_local_internal_base_Native_MQCONNX+0xcfbd4 568 Additional Symptom(s) Search Keyword(s):

Problem summary: A WMB broker address space using the MQ Java Interface, has the queue manager it has already connected to become unavailable, a residual value in the MQ Java native interface code being used in a MQ call. This results in attempting to access freed storage resulting in a GPF abend in the following Java callstack: com/ibm/mq/jmqi/local/internal/base/Native.MQCONNX Native callstack: CSQBBspiSCTX+0xd1d68950 (0x0000000000000000) ResetContextFn+0xcfbd12d0 (0x0000000000000000) Java_com_ibm_mq_jmqi_local_internal_base_Native_MQCONNX+0xcfb d4568 Problem resolution: The MQ Java native interface code has been altered to clear the residual values before MQ calls, so freed storage is not accessed for the WMB broker address space. This fix changes the Java component of MQ, and will be included in a FixPack APAR. The fix is targeted for delivery in the following PTFs: Version Maintenance Level v7.0 7.0.1.14 (PI34463 on z/OS) v7.1 7.1.0.7 (PI34462 on z/OS) v7.5 7.5.0.6 (Distributed platforms only) V8.0 8.0.0.3 (PI34470 on z/OS) Re The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 COMMENTS.41
