i had a situation where after launching an application, my NT 4.0 Workstation LOCKED UP tighter than an 8-day clock.  After doing a COMPLETE (reset button) reboot... i checked the event log and it said my RING BUFFER overloaded.

what causes this and how do i prevent it from happening again?

SYMPTOMS
========
 
When the number of mouse or keyboard events buffered internally by the
driver in nonpaged pool memory is too low, one of the following error
messages gets logged in the Event Viewer:
 
   Source      Category      Event      User
   -----------------------------------------
   Mouclass    None          11         N/A
 
   -or-
 
   Source      Category      Event      User
   -----------------------------------------
   i8042prt    None          12         N/A
 
Both of the above error messages have the following description:
 
   The ring buffer that stores incoming mouse data has overflowed (buffer
   size is configurable through the Registry).
 
RESOLUTION
==========
 
WARNING: Using Registry Editor incorrectly can cause
         serious, system-wide problems that may require you to
         reinstall Windows NT to correct them. Microsoft cannot
         guarantee that any problems resulting from the use of
         Registry Editor can be solved. Use this tool at your own
         risk.
 
Use the Registry Editor (REGEDT32.EXE) to edit the following entry:
 
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/i8042prt/Parameters
 
Make the value for KeyboardDataQueueSize and/or MouseDataQueueSize
larger.
 
NOTE: The default value for both of these is 64.
 
The above service (i8042prt) name may vary, depending the type of
mouse you are using.
