DOCUMENT:Q82318 10-MAY-2001 [win3x] TITLE :Stack Overflow Can Cause Windows to Hang PRODUCT :Microsoft Windows 3.x Retail Product PROD/VER:WINDOWS: OPER/SYS: KEYWORDS:kbProd2Web ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows versions 3.0, 3.0a, 3.1, 3.11 - Microsoft Windows Millennium Edition ------------------------------------------------------------------------------- SUMMARY ======= Stack overflows can cause Microsoft Windows to stop responding (hang). If Windows hangs intermittently, try adding the following line to the CONFIG.SYS file: STACKS=9,256 MORE INFORMATION ================ The addition of the STACKS command line causes MS-DOS to reserve space for hardware interrupt handling (rather than an application's stack). In general, the default setting gives you more free memory; however, there are situations when the hardware interrupt routines require more space. On IBM machines, STACKS=0,0 is the default; on all other machines, STACKS=9,128 is the default. One such situation is when you are running SMARTDrive (SMARTDRV.EXE) version 4.0 with certain network cards. Windows Setup should modify the CONFIG.SYS file accordingly when Windows is installed if it detects a known problem configuration. If Windows is hanging or crashing, particularly if SMARTDRV.EXE 4.0 is running, or a network is installed, try adding the STACKS command to the CONFIG.SYS file and see if that corrects the problem.
