SYMPTOMS
The SNA Server Manage Agent service (MngAgent.exe) may generate an
application exception error when APPC sessions are not properly
cleaned up.
When this problem occurs, the Windows NT Application Event Log
will contain
a message similar to the following:
Event ID: 624
Source: SNA Server
Description: Creating dump file C:\SNA\traces\snadump.log for
mngagent.exe
If Drwtsn32.exe is the default debugger on the computer running
Windows NT
Server and SNA Server, an entry similar to the following will be
included
in the drwtsn32.log in the Windows NT directory:
Application exception occurred:
App: exe\mngagent.dbg (pid=<process ID #>)
When: <date> @ <time>
Exception number: c0000005 (access violation)
CAUSE
Partner APPC sessions are not being cleaned up properly when SNA
Server
receives notification from a client to close an APPC session. This
eventually leads to the application exception error.
