.NET Questions and Solutions

Symptoms
If the SnaNetMn service is configured for automatic startup in ControlPanel/Services or if it is started manually, the following popup errormessage is displayed:

SNA Server – ERROR # 03…OK Note: This message will not appear in the application event log.
In addition, an application exception in Snanmvt.exe occurs that generatesa Dr. Watson log in the Windows NT directory. The entry created in theDrwtsn32.log file will be similar to the following:

Application exception occurred:App: exe\snanmvt.dbg (pid=<pid #>)When: <date> @ <time>Exception number: c0000005 (access violation)function: sepdnmsd_int[...]FAULT ->67241535 803a00cmpbyte ptr [edx],0×0[...] The following messages will be logged in the Windows NT Application Eventlog:

Event ID: 4097Source: DrWatsonDescription: The application, exe\snanmvt.dbg, generated an applicationerror. The error occurred on<date> @<time>. The exception generatedwas c0000005 at address 67241535 (sepdnmsd_int)Event ID: 624Source: SNA ServerDescription: Creating dump file <snaroot>\traces\snadump.log forsnanmvt.exe
Resolution
The application exception occurs because a corrupted buffer caused stackcorruption while attempting to display popup errors that contained longerror messages. The error message that results from starting the SnaNetMnservice contains a long description, which is why the application exceptionoccurs.
Note: Other errors may result in an application exception when a popuperror message is being displayed. These application exceptions may bereported against components other than Snanmvt.exe.

Symptoms
The SNA Server Manage Agent service (MngAgent.exe) may generate anapplication exception when stopping an LU. When this problemoccurs, theWindows NT Application Event Log contains a message similar to thefollowing:

Event ID: 624Source: SNA ServerDescription: Creating dump file C:\SNA\traces\snadump.log formngagent.exe.If Drwtsn32.exe is the default debugger on the Windows NT Servercomputer that is running SNA Server, an entry similar to the following willbe included in the Drwtsn32.log in the Windows NT directory:

Symptoms
SNA Server or Host Integration Server 2000 systems being used to distribute DLC 802.2 link services for use by branch SNA Servers and/or Host Integration 2000 servers in a Distributed Link Service (DLS) environment may experience an application exception in Snalink!UpdateDLSData.
NOTE: The problem only occurs when a DLS connection terminates unexpectedly. Therefore, the Application Event log may contain events normally associated with connection outages prior to the application exception. Common connection outage events logged by SNA Server/HIS 2000 include the following events: 23, 227, 226.
Resolution
The application exception occurs when a NULL message pointer is passed into the UpdateDLSData function.

Symptoms
An SNA Server computer using SNARAS may experience an application exceptionin Rasman.exe in function SnaRasUnbind() after successfully opening andclosing a number of SNARAS connections in succession.
An entry similar to the following will be written to a Drwtsn32.log file inthe Windows NT directory when the application exception occurs:

Application exception occurred:App: exe\rasman.dbg (<process id>)When: <date> @ <time>Exception number: c0000005 (access violation)<data omitted>function: SnaRasUnbind<data omitted>FAULT ->63701c81 8b7604mov esi,[esi+0x4]ds:014bfa0e=????????<data omitted> In one reported instance of this problem, the application exceptionoccurred after 20 to 30 SNA Server SNARAS connections were opened and thenclosed in succession. Each connection was established to download filesfrom a remote system and was closed after the files were downloaded.
Resolution
The application exception is caused when SNARAS attempts to access memorythat has been released.

Symptoms
When you are running an Advanced Program-to-Program Communications (APPC) or Common Programming Interface for Communications (CPI-C) application, you may encounter an Access Violation (AV) in DMODInitReceiveAllocate.
If Dr. Watson is configured as the default debugger, an entry similar to the following may be appended to the Drwtsn32.log file:

Resolution
The application exception is caused by a buffer overrun during Dynamic Load processing.
