Error description
WebSphere MQ .NET application running on Windows 2003 / 2008 terminates unexpectedly with an access violation in amqxcs2.dll, often after a specific number of MQExceptions have been caught. The NMQI class causing the exceptions seems irrelevant. A Microsoft Windows dialog box appears with the following problem signature: Problem Event Name: APPCRASH Application Name: your_mq_client_app.exe Application Version: 1.0.0.0 Application Timestamp: 4c65b77e Fault Module Name: MSVCR80.dll Fault Module Version: 8.0.50727.3053 Fault Module Timestamp: 4889d619 Exception Code: c0000005 Exception Offset: 00011733 OS Version: 6.0.6001.2.1.0.274.10 Locale ID: 1033 Additional Information 1: d75c Additional Information 2: a440d5025d98c8afd950784b5c53ce61 Additional Information 3: a0c0 Additional Information 4: 4bd33c35b3b1f78e475f38b93caad055

Problem summary
**************************************************************** USERS AFFECTED: All users of applications which use WebSphere MQ .Net classes and interfaces. Platforms affected: Windows **************************************************************** PROBLEM SUMMARY: WebSphere MQ .Net code uses exceptions and try-catch blocks to report errors and process errors. In some cases where an exception was caught trace buffer space previously acquired was not correctly released. After a series of exceptions trace data overflows the buffer usually resulting in an access violation.
Problem conclusion
Code was checked and modified to correct all of the instances of the problem that were found. However, it is possible that other instances still remain. | MDVREGR 7.0-WS-MQ-Windows-RP0001 | | MDVREGR 7.0.1-WS-MQ-Windows-FP0001 | | MDVREGR 7.0.1-WS-MQ-Windows-FP0002 | | MDVREGR 7.0.1-WS-MQ-Windows-FP0003 | | MDVREGR 7.0.1-WS-MQ-Windows-FP0004 | --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v7.0 Platform Fix Pack 7.0.1.5 -------- -------------------- Windows U200324 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 ---------------------------------------------------------------
