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.

Example 1.

  Event ID: 4104
  Source: Transaction Server
  Type: Error Category:
  Context Wrapper

  An object call caused an exception. (Package: BroncBuster)
  (ProgId: Library.Interface.1) (CLSID:
  {014A26B5-C2A4-11D2-81C2-0001FA37721E}) (Interface: IDispatch)
  (IID: {00020400-0000-0000-C000-000000000046}) (Method: 6)
  (Microsoft Transaction Server Internals Information: File:
  d:\viper\src\runtime\cw\cwlib.cpp, Line: 935) (Exception: C0000005)
  (Address: 0x77f051a9)
  KERNEL32!InterlockedExchangeAdd + 0x9
  tagen!Ordinal95 + 0x5477 tagen!Ordinal95 + 0x216F
  mtxex!DllUnregisterServer + 0xB393
  mtxex!DllUnregisterServer + 0x102EC

In the above description, "Library.Interface.1" is the ProgID of the COMTI
component library. Also, "Exception: C0000005" indicates an access violation.

Example 2.

  Event ID: 4104
  Source: Transaction Server
  Type: Error Category:
  Context Wrapper

  An object call caused an exception. (Package: CedarBank) (ProgId:
  Cedar.Bank.1) (CLSID: {EEB4EBF3-9A63-11D0-AB6F-00AA00C1479E}) (Interface:
  IDispatch) (IID: {00020400-0000-0000-C000-000000000046}) (Method: 6)
  (Microsoft Transaction Server Internals Information: File:
  d:\viper\src\runtime\cw\cwlib.cpp, Line: 935) (Exception: C0000005)
  (Address: 0x77f0515a)
  KERNEL32!InterlockedIncrement + 0xA
  mtxex!DllUnregisterServer + 0xB393
  mtxex!DllUnregisterServer + 0x102EC

Example 3.

  Event ID: 4104
  Source: Transaction Server
  Type: Error Category:
  Context Wrapper

  An object call caused an exception. (Package: TestVB)(ProgId:
  TestPilote_COMTI.MCVB.1) (CLSID: {8D79A611-E784-11D2-9BD2-0008C7F7EC7C})
  (Interface: _MCVB) (IID: {8D79A600-E784-11D2-9BD2-0008C7F7EC7C}) (Method:
  6) (Microsoft Transaction Server Internals Information: File:
  d:\viper\src\runtime\cw\cwlib.cpp, Line: 861)

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.
