After Upgrade to SNA Server 4.0 SP2, COMTI Application Fails With "Out of Memory" Indication

• Microsoft COM Transaction Integrator for CICS and IMS, version 4.0 SP2
• Microsoft SNA Server, version 4.0SP2

SYMPTOMS

Upon invocation of a method of a COMTI component library, an "Out of memory" message is returned to the client application, and Microsoft Transaction Server writes event 4104 to the application event log. The following are examples of such event log entries.

The first two examples contain "eyecatchers": "KERNEL32!Interlocked..." and "(Exception: C0000005)." However, these are not necessarily present, as in the third example below.

CAUSE

COMTI runtime components try to manipulate Performance Monitor object counters in shared memory. The shared memory does not have appropriate access tokens, which leads to an access violation. The access violation is caught by Microsoft Transaction Server (MTS), which causes the "Out of memory" message to be presented. Simultaneously, MTS writes an event 4104 record to the Event Log.

RESOLUTION

To resolve this problem, obtain the latest service pack for SNA Server version 4.0. For additional information, please see the following article in the Microsoft Knowledge Base:

STATUS

Microsoft has confirmed this to be a problem in COM Transaction Integrator for CICS and IMS, version 4.0 SP2. This problem was first corrected in SNA Server version 4.0 Service Pack 3.
