We have had to make our event logs large because an attack can fill up the 
log with invalid login attempts.

However, I saved the log to file, reduced the size, then cleared it. The 
next attempt was *successful* - Initial check: setting values. So I guess 
there is a practical upper limit to the event log sizes, and if we need to 
save historical data, then we'll have to export and clear periodically.
