Article ID: Q138611
The information in this article applies to:
  • Microsoft SNA Server for Windows NT, version 2.11

SYMPTOMS

An application exception (trap) occurs in the SNA Server 802.2 Link Service when you stop SNA Server version 2.11. If DRWTSN32.EXE is configured as the default debugger, the DRWTSN32.LOG includes an exception similar to the following: 

   Application exception occurred:
      App: snalink.DBG (pid=169)
      When: 08/2/1995 @ 1:54:25.364
      Exception number: c0000005 (access violation)
In addition, SNA Server logs Event 624 in the Windows NT Event Viewer Application Log when this trap occurs. The following is a detailed description of the Event 624 that is logged when the exception occurs:

Creating dump file C:\SNA\TRACES\SNADUMP.LOG for SNALINK.EXE

EXPLANATION:

A process (SNALINK.EXE) ended abnormally due to a protection violation or similar condition and a dump file SNADUMP.LOG has been created that contains information about the state of the process at the time of the exception. Register information is contained in your Windows NT root directory in the file DRWTSN32.LOG.

CAUSE

The application exception is caused when the 802.2 Link Service tries to access a pointer to a LCB after it has previously been freed.

RESOLUTION

Microsoft has updated the follwing files to correct this problem: 

   <snaroot>\SYSTEM\SNADLC.DLL
   <snaroot>\SYSTEM\HWSETUP\SNACLASP.INF
