Problem summary
**************************************************************** USERS AFFECTED: All users of WebSphere MQ v7.0.1 Java applications Platforms affected: All Distributed (iSeries, all Unix and Windows) +Java **************************************************************** PROBLEM SUMMARY: WebSphere MQ Java layer passes on a request to the queue manager to write an FFST. In order to write an FFST, WebSphere MQ allocates a buffer for java stack string. This buffer allocation was incorrect thus causing a heap corruption.
Problem conclusion
WebSphere MQ v7.0.1 code has been modified such that the buffer allocation for java stack string is done correctly while writing FFST. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v7.0 Platform Fix Pack 7.0.1.10 -------- -------------------- Windows U200352 AIX U853055 HP-UX (PA-RISC) U853082 HP-UX (Itanium) U853087 Solaris (SPARC) U853083 Solaris (x86-64) U853089 iSeries 7.0.1.10 Linux (x86) U853084 Linux (x86-64) U853088 Linux (zSeries) U853085 Linux (Power) U853086 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 ---------------------------------------------------------------
