DESCRIPTION

When upgrading to OS/2 Warp or OS/2 Warp Fullpack, the following error 
message is received:

   SYS3171: Insufficient stack space PMWP.DLL 0001:001c64d

The failure occurs on systems that were upgraded from previous OS/2 
releases without the hard disk being formatted.

After successfully installing OS/2 Warp or the OS/2 Warp Fullpack
upgrade, the correct Desktop appears after restarting the system.
However, after a successful shutdown, all subsequent restarts result in:
                          
   SYS3171
      A program caused exception c0000005 at 1bebe64d.
      Due to insufficient stack space, the exception was not
      dispatched.

RESOLUTION

Some folders are populated several times when the system is upgraded 
from a previous version of OS/2. This causes the system to run out of 
stack space. The OS2.INI and OS2SYS.INI files get damaged and need 
rebuilding.


Rebuilding Files without Saving Customization
---------------------------------------------
If there is no concern about losing all customization, perform a 
destructive MAKEINI as follows:

1. Restart the system from the OS/2 Installation Diskette:

   a. Perform a shutdown.

   b. Insert the Installation Diskette in drive A and restart the 
      system.

   c. When the logo screen appears, remove the Installation Diskette
      and insert Diskette 1.

   d. Press Enter.

   e. When the "Welcome to OS/2" screen appears, press Esc.

2. Change to the drive where OS/2 is installed.

3. Change to the \OS2 directory.

4. Type the following, pressing Enter after each, to rename the current
   OS2.INI and OS2SYS.INI files:

      RENAME OS2.INI OS2INI.BAK
      RENAME OS2SYS.INI OS2SYS.BAK

5. Type the following, pressing Enter after each, to re-create both INI
   files:

      MAKEINI OS2.INI INI.RC
      MAKEINI OS2SYS.INI INISYS.RC

6. Remove any diskettes from the diskette drive; then restart the
   system.


Rebuilding Files Saving Customization
-------------------------------------
If you do not want to lose all customization, find the folders that were
populated multiple times. Open each folder on the Desktop to locate 
duplicate folders. For example, multiple DOS Programs folders might be 
embedded within the folder appearing on the Desktop. Duplicate folders 
might also be in the FFST/2 and UPM folders.

Delete the duplicate embedded folders.
