SYMPTOMS
========

An SNA Server computer using SNARAS may experience an application exception in
Rasman.exe in function SnaRasUnbind() after successfully opening and closing a
number of SNARAS connections in succession.

An entry similar to the following will be written to a Drwtsn32.log file in the
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>

In one reported instance of this problem, the application exception occurred
after 20 to 30 SNA Server SNARAS connections were opened and then closed in
succession. Each connection was established to download files from a remote
system and was closed after the files were downloaded.

CAUSE
=====

The application exception is caused when SNARAS attempts to access memory that
has been released.
